As more homeowners have recognized the need to properly seal their home to improve energy efficiency, the resulting effect has been a dramatic reduction of indoor air quality. Replacing the heating and cooling system of your home can be very costly, but there are ways to help improve the indoor air quality without going to such expense.

For existing systems, your best bet is to replace the air filters with a two or even three-stage filter. With these new filters, it is now possible to control harmful airborne microorganisms, gasses and even dust particles.

While not readily available at all hardware stores, many of these filters can be purchased online. Be sure to look for high density carbon or polycarbon in the item’s description. You can also improve the quality of air in your home by using these filters in conjunction with a stand alone room ionizer.

  1. My husband suffers from asthma and allergies. We use the best filter that 3M makes MERV12 Ultra Allergern. Can you give us advice on whole house purification systems for the hvac. We built this home 3 years ago. We have a limited amount of space at the unit for installation.
    thank you

  2. There’s a lot of controversy surrounding these systems, Sarah. The 3M filter is great. However, if you want to look into a whole house air purification system, be prepared for a shock to the pocketbook. They can be expensive. You could start with your local Trane and Lennox contractors, but I would recommend going to the consumer site of the American Indoor Air Quality Council first. They are a national non-profit organization with certified installers listed throughout the U.S. Their site is: http://www.iaqcouncil.org/Consumers/consumers.htm. You may also want to check out a study done by Penn State on ultraviolet light in conjunction with air quality. It’s pretty interesting what they are claiming. You can get to their study here: http://www.calutech.com/. With limited space, your options may be limited as well, but these web sites are a good place to get the answers you need! Happy hunting!

  3. During the winter our windows sweat so bad we have to dry them with towels every morning. It’s very bad, it makes the paint pell around the window . Is there anything that can be done. During the summer we don’t have a problem . Please let us know what we can do.

  4. Sue,
    This common problem is caused by condensation of the warm inside air against the cold glass. While reducing the humidity inside your house might help, the best solution is to install storm windows. Before you do though, check the old windows for spots where the outside air may be getting in and weather strip or caulk them as necessary. Another more costly solution would be to replace the existing windows with new ones that are energy efficient and have insulated glass.

  5. Our heating system does not use a ductwork system. I am concerned about air quality and would like info on stand alone ionizers or any other system that improves air quality without ductwork.

  6. We need to replace our present heating and air system. They cost so much. Is there a website that I could visit to see if the quotes I’m getting is correct? Also, can you have the heating and air put in at different times? I live in B. R., LA.

    Not all whole home air cleaning systems are costly. One can get an AspenAir Inside for under $1,000. It is continuously high-performing – unlike other whole home and room-only systems.
    It can be bolted on any home hvac system, requires less than 1-minutes of maintenance each year (1-2 filter changes) and does not emit harmful ozone.

    Most importantly it removes from one’s home air the tiny particles that go deep into your lungs, the RSPs that make asthma and other allergies much worse.
