Whole House Air Filters Remove Pollen, Second-Hand Smoke and More

In many parts of the country, fall is the time of year when ragweed and other pollen-producing plants go into high gear.  Individuals who suffer from allergies often benefit from better filtration of their indoor air.  In addition to filtering out plant pollen for allergy relief, the right system will also remove second hand smoke, odors, pet dander, dust and many other irritants.  Early fall, when the heat of summer subsides, also happens to be one of the two slower periods each year for most local AC and heating companies.  The convergence of these facts makes a good topic for our post today.

In contrast with portable or room air filters, a whole house air filtration system covers all rooms of your home and are integrated within your HVAC system.

Within your AC and heating system, the air filter element serves two main purposes:

1– Protect your AC and heating equipment from contamination and becoming clogged inside the system.  The air filter element must allow the air to flow through the equipment at the rate specified for that system. Of course, if the filter is not changed on schedule the clog will occur at the filter element itself.

2– Remove airborne particles, odors and other contaminates from the indoor breathing environment of your home or office.

There are many choices of whole house air filters available.  Just as in water filters, the overall objective is to remove the maximum amount and type of contaminates while avoiding undesirable growth of molds, etc. on the filter media.  Maintenance requirements, initial + operating costs, and other factors figure must also be included in this equation. For a more detailed description, go to our air filter page.

During autumn, your local AC and heating service companies are less busy.

For the homeowner, this means that now is a good time for you to call them for maintenance, repairs, or to get a quote on an air filter system.  They will be under less pressure (which is usually the case when it first gets hot or cold outside), plus many service companies offer off-season discounts, rebates, and other ways to save.

If you are about to get a new ac and heating system or make changes to your air handler or ductwork, you will want to consider the air filter options at the same time.  It costs less to add a whole house filter at these times, rather than as a stand-alone project later.  As is the case in the rest of air conditioning and heating, the quality of the installation often makes a bigger difference than the brand of equipment.  Of course, there are differences in air filter equipment.  However, you need to first screen for quality work from the company who will install and maintain it for you, because that is the most important variable. While on site, your local HVAC contractor can also help you select the equipment that will work best to meet your indoor air quality goals in the physical situation within your home or building.
