Whole-House Air Purifier for HVAC System

The Environmental Protection Agency (EPA) has stated that indoor air quality can be two to five times worse than the outdoor air quality of a metropolitan city. That might be enough of a reason to consider installing an air purifier in your house. And if you want the most effective one, most experts will suggest a whole-house air purifier in your HVAC system.

How Whole-House Air Purifier Works

If you need your air purifier to run occasionally, a portable unit might be enough. But if you need a constant purifying, it is advisable to install a whole-house air purifier in your HVAC system. Overall, the system is more effective and longer lasting than a portable device.

A whole-house air purifier system sits on the return duct of your HVAC system. This means the air that enters your house will pass through it. Any contaminants will be trapped by the filters. Hence, only clean air will enter the room.

Which Type of Whole-House Air Purifier Is the Best?

There are many kinds of technologies that can purify the air. Each of them has different ways to clear out contaminants. Here are the most common ones:

1. Flat Filters

Flat filters are commonly built into AC units. The thin layer can be effective for a few types of particles, but smaller particles may still pass through. For most houses, flat filters are enough to maintain indoor air quality. You will need other filters if you have one or more of these conditions:

● Your house produces more indoor air pollutants than regular houses
● Your house has a terrible ventilation system
● One or more of your family members have allergies or respiratory problems due to a hypersensitivity to a kind of airborne particles.

2. Extended Media Filters

An extended media filter is an added filtration system you can install in your HVAC system when flat filters are not enough to clean your indoor air. The technology can trap smaller pollutants that flat filters can’t. This type of air purifier can be useful to produce clean air at an affordable price.

3. Electrostatic Precipitator

Electrostatic precipitators use electrical induction charges to remove pollutants from the air. This system can be effective for tiny particles like dust and smoke, which are difficult to catch with other types of filtration systems. Unfortunately, this type of air cleaner costs quite a lot.

4. UV Air Cleaner

UV air cleaners are more effective for organic contaminants such as fungi, viruses, and bacteria. The radiation can break their shell and turn them inactive. This type of air purifier is best for allergies, mold, or hypersensitivity to certain types of microorganisms.

Which type of air purifier is best for your house depends on what kind of contaminants you are most concerned about. If you have multiple concerns, you can consider buying a hybrid air purifier. These contain two or more air-purifying technologies to deliver even higher-quality indoor air for your home.
