Benefits of Whole House Air Purifiers

Air Is Clean

If you spend a lot of time at home, such as if you work from home or are a stay-at-home parent, clean air might be beneficial. You may boost your productivity by enhancing the air you breathe.

When the quantities of airborne contaminants inside your home grow too high, you might rapidly become tired and sluggish. You may find that you are tired most of the time, or that you have regular headaches. All of these might be indicators of poor indoor air quality.


If you suffer from allergies or asthma, an air purifier can significantly improve your health. Indoor contaminants such as dirt, dander, and hair, among others, are most likely to blame for your symptoms.

Most air purifiers can efficiently remove particles as tiny as 0.3 microns, which can help alleviate your symptoms. Even better, if the machine has the proper filter, it can catch 99.97% of the particles.

Increase HVAC Efficiency

A whole-house air purifier does more than merely enhance the quality of your air. It may also keep airborne particles out of your HVAC system, which can cause it to slow down and break down. As a consequence, you may anticipate a more efficient HVAC system that will last even longer than you anticipated.

Eliminate Mold and Dust

Seasonal allergens are aggravating enough, but if you suffer from year-round allergies to mold, dirt, or pet dander, you need a comprehensive solution that covers every inch of your house. A high-end device, like the Lennox Healthy Climate Carbon Clean 16 Media Air Cleaner, accomplishes all of this and more. It eliminates 95% of particulates from the air, including germs and viruses, allowing you to breathe comfortably in any season.

You’ll Sleep Better

Poor indoor air quality might disrupt your sleep. Dust and other particles can contribute to snoring and impair the effectiveness of your sleep. Polluted air can cause sudden infant death syndrome in newborns in extreme situations (SIDS). As a result, by enhancing the quality of the indoor air, you can reduce the likelihood of developing sleep problems. Overall, you’ll have a restful night.

Filter Out Seasonal Allergens With Air Purifiers

If you or a family member suffers from seasonal allergies, you may experience sneezing and sniffling from spring through fall. While you can’t escape pollen from trees, floors, or IEDs outside, you can surely keep it out of your house.

I recommend whole-house air purifiers for allergy patients at Willard Heating and Air Conditioning since these devices do so much more than an air filter or a portable air cleaner. Whole-house air purifiers operate in tandem with your HVAC system to remove pollen and other seasonal allergens from your home’s air supply.

How to Choose the Best Whole House Air Purifiers

Here are the qualities to look for in a device that will keep the air in your entire home clean.

Size of Home

Whole-house air purifiers may cover a large area. You may buy ones that are linked to your HVAC system. Today, though, I concentrated on portable devices that may cover an entire house.

I shall provide the coverage capacity of each air purifier. Determine the size of your home and buy appropriately. Our recommendations range in size from 1100 to 3700 square feet.

Choose one that can cover a few additional square feet than your home for the greatest effects. This will guarantee that you have complete coverage.

Noise Levels

A loud appliance, especially one that operates continuously, is a nuisance. However, not all air purifiers are silent, and larger ones tend to make more noise as well.

Almost all air purifiers will display their noise levels from the lowest to the maximum. If it isn’t included in the description, browse down to the reviews and other consumers will undoubtedly tell you of how loud it is.

It’s a good idea to get a bigger unit if you have a noise problem.

It may seem paradoxical, but bigger units may frequently be operated in a lowerand quieter setting. In large households, smaller equipment needs to operate at a faster rate. Unfortunately, this generally results in increased noise.

Filter Type

The filter is responsible for the air purifier’s success. The air will not be cleansed if the filter is of low quality or does not have enough filtering stages. HEPA and activated carbon filters are the finest to search for.

HEPA filters filter out the smallest contaminants in the air. Dust, dust mites, pollen, and mold are among the pollutants that HEPA filters can remove.

But for smells, you’ll need an activated carbon filter. Among other things, they may gather chemicals, gas molecules, formaldehyde, and other odors.

Fortunately, the majority of whole-house air purifiers employ both. The disadvantage is that they will ultimately need to be replaced, which may be costly.


If something goes wrong, warranties allow you to replace broken parts or even the entire item. When a manufacturer offers a guarantee on their products, it indicates that they stand behind the quality. Having a good one typically indicates that the product is worth its price.
