Orange County HVAC Tip: How Electronic Air Filter Works

Monday, April 2nd, 2012

For a long time, the most frequently used kind of air filter has been the mechanical variety, and it probably what you already have in your Orange County HVAC system. This is the kind you probably think of when you hear the terms air filter, air cleaner or air purifier. They use pleated fibrous filters in-line with an air handler to trap particles in the air before circulating it back out into the home.

Many models of these work very well and have for many years. They have the added benefit of being flexible because you can put in whatever filter you need depending on what size particles you need to trap.

However, these traditional devices are not the only option. A second kind of air filter exists for trapping particles in the air– one that does not use a fibrous filter that physically snags them out of the air on the way through.

These electrostatic — or electronic — air cleaners work in a different way to produce a similar result. The filtering component is still a fibrous sheet, but the difference is that the fibers are made of plastic, which becomes charged when air passes through it and causes friction.

(Think something like when you rub a balloon and stick it to the wall.)

These friction-charged fibers carry an electronic charge, which attracts the ions in the air around it. These ions — and the particles that they are a part of — get trapped in the fibers and stay out of your air supply.

 Electronic air filters are generally very good at trapping particles that are 1 micron in size or higher, putting them about on par with a mechanical air filter that carries a MERV rating of 12. The electrostatic method works well for many common household air pollutants, such as dust, pollen, mold and pet dander.

As with many ventilation-related decisions, the choice of what kind of air filter is right for your Orange County air conditioning and heating system depends on your needs and those of your family. If you are having trouble deciding, then an air quality assessment and consultation with Saddleback Plumbing, Heating & Air Conditioning can be a good way to reach a decision.

Types of Humidifiers for Orange County Homes

Friday, February 10th, 2012

Even when you know you need a humidifier for your Orange County home, it’s hard to pick out just the right model. Humidifiers aren’t terribly complicated pieces of equipment, but they do have subtle differences that make one type more appropriate for your home than another. That’s why it’s a good idea to learn a bit about your humidification options before you go out and buy a humidifier. It’s also helpful to talk to an HVAC professional about your options so you know better how to select the right humidifier for your home.

One of the first decisions you’ll make when shopping for humidifiers is whether you want one that produces warm or cool mist. Both types of humidifier are appropriate under certain circumstances, so you’ll have to take the particulars of your home and situation into account when making your decision.

Warm Mist Humidifiers

Warm mist humidifiers are an excellent choice if you regularly battle dry air in the winter months. Because a warm mist humidifier needs to heat the water, it generally uses more energy than a cool mist unit.

Some warm mist and steam humidifiers can also cause burns because the water vapor is very hot when it comes out of the unit, so it’s important to keep kids and pets away from these types of units. Larger humidifiers can be installed in out of the way places such as your basement to reduce risks, but it’s still a good idea to discuss your options with a professional before installing a warm mist model.

Cool Mist Humidifiers

Cool mist humidifiers, on the other hand, use very little energy because they don’t actually heat the water they introduce to the air. There are several methods that cool mist humidifiers use to turn water into water vapor including a wick, an impeller and an ultrasonic system. If you have small children or if you need to humidify a large area in your home, a cool mist humidifier might be just what you’re looking for.

These units are usually cheaper to run than their warm mist counterparts, but they are also noisier and their air filters need to be changed regularly. That isn’t as much of a problem with a warm mist humidifier, however. Because you heat the water before it is spread throughout your home, most contaminants are removed or killed and filtration isn’t as important.

Whichever type of humidifier you choose, rest assured that your family will be more comfortable and healthier all winter.  If you need any more help with making this decision please contact Saddleback Plumbing and Heating.

When Should You Check Your AC Filters in Orange Country

Friday, February 3rd, 2012

In Orange County the filters on your air conditioning unit are vital for keeping out the dust and debris that make things like illness, allergies and air quality worse. And it’s important that you take personal responsibility for checking those filters. Sure, you have a professional visit your home once a year to check the air conditioning, but you should also check the indoor air quality yourself on a semi-regular basis for possible filter degradation.

Monthly Checks

So, how often should you check? Think of it this way. There is no such thing as checking too much, but you can easily not check often enough. So, we recommend checking your filter at least once every 4 weeks. It may not always need to be changed during that four week checkup (sometimes it can last 6 weeks or longer), but it’s good to take a peek.

Why is this so important? Because filters that haven’t been checked and changed as needed have a habit of building up excess sediment and debris. Not a problem when it comes to actually working, but a huge problem when it comes to your energy bill. The harder a system has to work to keep you house cool, the more energy it draws and the more you pay to have cool air in your home. And it will break down much faster as a result of overwork and dirty filters.

Changing an AC Filter

If your filter is ready for a swap, here are some quick tips to get the job done:

  • Find Your Filters – If you don’t know where your filters are, ask your contractor on the next visit or look near the return grills by the thermostat.
  • Remove the Filters – Open the latches and pull the old filter out to check it. You should be able to see clearly through a permanent filter and a disposable one should still be white. If this isn’t the case, it’s time for a cleaning/replacement.
  • Clean the Area – Clear the grill and area of any debris and sediment that might make the filter worse after replacement.

Proper filter maintenance only takes five minutes and it will save you money every month you run your AC – not a bad deal for a few minutes’ work.

Will My Air Cleaners Reduce Health Risks? A Question from Mission Viejo

Friday, November 18th, 2011

There is a lot of talk these days about how important it is to have a good air cleaner in your Mission Viejo home. If you don’t have one, you’re putting yourself at risk, or so says common knowledge. But, do air cleaners really reduce health risks, and if so, by how much?

What Air Cleaners Do

Before we can say whether an air cleaner has any positive health effects, we must first look at what they do. Air cleaners are designed to remove certain particles from the air inside your home. Different air cleaners are designed for different levels of removal.

Ratings like the MERV of an air cleaner measure how small of particles the device can remove. Additionally, the type of cleaner will determine what it is best at removing. Mechanical filters are the most efficient at removing dust, pollen, and dander while electronic filters are best for smoke, bacteria and mold spores.

So, What Impact Does this Have on Health?

The big question then is what kind of health benefits you will gain from a high end air cleaning system. If your home isn’t prone to a large number of contaminants and you have good ventilation, the difference may not be that big, but for those with a well-sealed home, pets, humidity problems or any number of other indoor air contaminant sources, an air cleaner has a tremendous impact on your health.

The problem is that when the house gets sealed up so tightly, we put our bodies at risk of contamination from gasses and pollutants that would otherwise dissipate into the air. Those with asthma are put at an increased risk as they breathe in a variety of different triggers like dust, mold and dander.

An air cleaner removes these threats and while they don’t have a proactive effect on your health – you won’t suddenly lose weight or never again get the flu – they can remove many of the negative effects that poor air quality has on your body.

Happy Halloween Weekend! (and Surprising Sources of Indoor Air Pollution)

Friday, October 28th, 2011

Everyone from Saddleback wishes you a Happy Halloween Weekend! Have a spooky (but safe) time!

Our scary warning of the day is about indoor air pollution. Indoor air pollution is a major problem for millions of homeowners throughout the country each year, and some of them live in Fountain Valley. In fact, the EPA estimates upwards of 20 million households may have problems caused by mold, radon, humidity, exhaust or any number of other pollutant problems. However, not all of the indoor air pollutants out there are so obvious. Some are things you probably have in your home right now and don’t realize it. Here are some of the more surprising sources of indoor air pollution and what you can do about them:

  • Incense – Incense releases both carbon monoxide and benzene, two chemicals that are potentially harmful to human health. Cancer, skin irritation and asthma risks are all increased in people who spend a lot of time around incense.
  • Laser printers – Laser printers that use toner can release a number of harmful chemicals into the air. That toner is very fine and releases particles into the air that are equal to or in some cases worse than second hand cigarette smoke. If you have a laser printer, consider putting it in a well-ventilated, infrequently used space.
  • Kitchen Stove – If you have a gas stove, it releases Nitrogen Dioxide when on, an unsafe gas that is odorless and fills your home quickly. This gas is bad for respiration and can cause asthma attacks. To solve this problem, simply make sure you stove is ventilated properly when cooking.
  • Spackle – Old spackle – the kind used before the 1980s often contained asbestos which can still be there, waiting to be disturbed. Old asbestos, while not inherently dangerous, will become so if you start doing work in your home or if the spackle starts to wear away. To solve this problem either call an abatement firm or cover the offending wall with a new layer.
  • Drapes – Those drapes are filled with contaminants that cling there, especially if humidity is a problem in your home. Dust mites in particular are bad for your health and can cause asthma and other allergies. Blinds are better than drapes for this reason.

Your home is filled with potentially dangerous problems, but you can avoid them simply by taking care to ventilate, clear away unsafe products and keep things like drapes clean (or remove them). If you’re still concerned about your air quality, call an expert to investigate.

What is Air Purification? A Question from Garden Grove

Wednesday, October 26th, 2011

The air around us is getting more and more polluted these days in Garden Grove, and people are trying to do more and more to combat it. Cars come with ratings like “ultra-low emission vehicle” and windmills generate power from moving air rather than burning coal. No doubt, these efforts help, but if you want to take an active role in improving the quality of air in your own home, consider an air purification system.

Simply put, air purification is the process of removing contaminants and pollutants from the air. There are a number of devices on the market that can purify the air in your home. While anyone can enjoy the benefits of cleaner air, they are of particular utility for people which suffer from asthma or allergies, or who live in areas with higher concentrations of outdoor air pollution.

There are three main kinds of air purifiers, categorized by the kind of technology they use:

  1. HEPA filtration
  2. Negative ion generation
  3. Electrostatic precipitation

HEPA filtration purifiers simply filter the air that passes through them using a sieve-like filter or series of filters. Depending on the efficiency of the device and the filter, some of these purifiers can trap not only solid and like particles, but also gases and odors. One advantage of this type of purifier is that the HEPA filters can last for years before they need to be changed.

Negative ion generation and electrostatic precipitation models are more complicated and technical because of the technology they use. Consult with a professional to choose which kind of technology is best for your needs, depending on the air quality problem you are experiencing. Some air purifiers can trap bacteria, viruses, fungi or chemicals, so there is bound to be one that will suit your needs.

After deciding on which type of technology you need, you will also have to choose whether you want a portable air purifier unit or a central system that covers the whole house. Obviously the former works well if you are only concerned about the air in a room or two, while the latter is better if you have chronic asthma or a more widespread air quality problem.

Where to Turn for Your Indoor Air Quality Concerns: A Tip from Robinson Ranch

Friday, October 21st, 2011

The quality of the air inside your Robinson Ranch home is incredibly important. It has a direct impact on the health and wellbeing of your family and in some cases can affect the cost of your heating and cooling. But with so many worries out there and so many people trying to offer advice, where do you turn when you need help? Here are some resources to help you if you’re worried about indoor air quality.

  • EPA Resources – The US Environmental Protection Agency provides a huge number of resources for homeowners and business leaders worried about indoor air quality. The EPA keeps a complete list of hotlines and clearinghouses to call depending on where you live at http://www.epa.gov/epahome/hotline.htm as well as a list of state health department resources according to their 10 region breakdown of the country at http://www.epa.gov/iaq/whereyoulive.html.
  • Asthma Help – If you suffer from asthma and are looking for help from an expert to handle an attack or deal with conditions leading to your attacks the Asthma No Attacks hotline is available both online at www.noattacks.org or offline at 1-866-NO-ATTACKS. The Allergy and Asthma Network is also available at www.aanma.org and the American Lung Association has a number of useful resources for anyone concerned with their lung health at www.lungusa.org.

Allergens Affected by Indoor Air Quality Systems: A Guide from Irvine

Wednesday, October 19th, 2011

Indoor air quality devices are designed to capture and remove certain allergens from the air, but what exactly is being removed and how would those allergens affect your health if left to circulate in your Irvine home? Here is a quick rundown of common allergens found inside the average home and why you should have them removed:

  • Dust Mites – Dust mites develop in high humidity conditions – above 50%. This means that dehumidification (which can be done with an air conditioner) to a healthy range between 35-50% will keep them from developing and ensure your indoor air stays comfortable and safe. Dust mites are not dangerous but they can severely increase complications from asthma and other uncomfortable conditions.
  • Animal Dander – Dander from cats, dogs, birds and other furry or feathered creatures is a common allergen for millions of people. If you suspect dander as an allergy, go on vacation to a place without dander and see how it affects you or your loved ones.
  • Dust and Dirt – Dust is in every home and while it is a common irritant, it can inflame asthma or worsen allergies many times over.
  • Pollen – Pollen is a problem for anyone with seasonal allergies or hay fever. While medicine can help, proper sealing of your house and indoor air filtration can reduce the presence of pollen from clothing and animals.
  • Bacteria and Viruses – Bacteria can develop in the air from common colds, old food or outside contaminants. Use a UV light to remove these from your air handler or ductwork.
  • Smoke and Exhaust – Indoor/outdoor ventilation can allow in smoke and exhaust that irritates most lungs. To avoid this problem install an electronic air cleaner that can target particles in smoke.

Getting rid of allergens in the air is an important aspect of maintaining a clean and healthy household. Proper air cleaning, filtration and UV purification will reduce these allergens many times over. There are also some great tips on the Asthma and Allergy Foundation website for how to reduce the presence of those allergens to start with.19

How Can I Be Sure My Home’s Air is Safe? A Question from Santa Ana

Monday, October 17th, 2011

There are many ways to ensure your Santa Ana home’s air is safe to breathe, but the easiest is to have it tested regularly and to use proper filtration and ventilation. However, there are a lot of different filtration methods, so here are a few known to work best.

Air Filtration

If you have pets or a lot of plants, air filters are a great idea because they remove most of the larger particles that get into our air supply. This includes things like pet dander, pollen, mold, and other particles like dust. If you have allergies or someone in your home has asthma of any kind, this is the best way to be sure they don’t breathe anything they shouldn’t.

Air filtration is also very simple to install and inexpensive to maintain. Just be sure you opt for HEPA air filters. They are the best on the market and are certified to capture much smaller particles than any other filters, plus they tend to last quite a bit longer.

Air Purification

For big time air cleaning, you want to go with an electronic air purifier. These machines will actually ionize the air in your home to separate out smaller particles such as gas, smoke, or pathogens like bacteria and viruses. They can also capture some larger particles like mold and dust mites. The key to effective air purification is to use it in conjunction with a good air filter.

Also, consider the use of a good UV filter with your air purifier. UV filtration can be installed in your air ducts or vents to kill any unwanted pathogens as the air is circulated.

How Bad Is the Air in Your Home? A Tip From Irvine

Wednesday, October 12th, 2011

Every day in Irvine you hear about another awful contaminant that can get into your home’s air supply. Radon gas. Carbon Monoxide. Nitrogen Dioxide. Smoke. Mold. The list gets longer with each passing year and many homeowners are understandably worried. However, before you run out and by the newest lineup of filters, purifiers, and UV lights, stop and think about just how bad your indoor air actually is.

When Was Your Home Built?

Homes built in the last 10-15 years tend to be well ventilated and may even have air quality systems already in place. It’s those built in the late 1970s and early 1980s that tend to have the worst ventilation (assuming they have not been updated since then).

This kind of poor ventilation can be dangerous, but usually only in that you have less fresh air and more indoor allergens and contaminants. Specifically, you’re most likely to suffer from things like pet dander, dust, pollen, and dirt in the air. On their own, these are not dangerous, but without fresh air to circulate them outside and ensure you get a steady, clean supply of air to breathe, they can make you ill.

How Bad Can It Get?

While it’s rare, some homes suffer from more advanced contaminations. The most common is mold. Mold grows primarily in dark, damp spaces. If your humidity levels get too high in the summer, the ductwork in your house is perfect for mold and it will blow the spores directly into your air, putting everyone at risk.

Outdoor contaminants can also make it into your indoor air. Things like exhaust and smoke, gas, radon, or other outdoor pollutants should be tested for when you setup a new indoor air quality system. There are filters and purifiers that will remove almost all of these contaminants, but they are not always required, so you should check before making a decision.

Ultimately, the odds are that your home suffers only from some stale, dusty air. But, it is very important to keep everything clean and test it regularly to make sure nothing worse develops. Poor air quality is about more than just comfort – it’s an honest health issue.
