It is important to keep your home free of visible dust and dirt, not only for your own eyes, but also for your comfort. But what about what you can’t see?

Your home has many particles floating in the air you breathe. Pet dander can aggravate allergies and asthma, while cigarette smoke causes cancer. Even if you’ve never picked up a cigarette, breathing in secondhand smoke can have negative consequences.

So it’s obvious that keeping the atmosphere in your home clean is crucial. One effective way to keep the indoor air clean is to use an air purifier. These come in all sizes, so today we focus on the best air purifiers for the whole house.

Advantages of Air Purifiers for the Whole House

Better Productivity

In the event that you spend a lot of time at home – perhaps working from home or staying at home – a clean atmosphere can help.

As indoor air pollution levels get too high, you can quickly become exhausted and sluggish. You may find that you feel sleepy most of the time or suffer from frequent headaches. All of these could be indications of a poor indoor environment.

Improved health

If you suffer from allergies or asthma, air conditioning can have a significant impact on your well-being. Indoor pollutants such as dust, dander, hair, etc. are most likely the culprits of your symptoms.

Since most HEPA whole house air purifiers can efficiently remove particles as small as 0.3 microns, they can improve your symptoms. If the machine employs the right filter, much better – it can collect 99.97 percent of airborne pollutants.

Superior sleep

Poor indoor air quality can disturb your sleep. Dust and other particles can cause snoring and affect the efficiency of your rest. For babies, polluted air can cause sudden infant death syndrome (SIDS) in severe cases.

Remember: for best results, select an air purifier that can cover a few extra square feet more than your home. This will guarantee the unit can cover the whole area of you home.

Noise level

Owning a noisy unit is troublesome, especially one that runs 24/7. However, not all air purifiers are quiet and the larger models also tend to produce more noise.

Virtually all air purifiers will tell you their noise level from the bottom to the maximum setting. If it’s not in the description, scroll down to the reviews and other users will surely let you know how loud it is.

To combat a noise problem, it’s a good idea to buy a larger unit.

It may seem like contradictory advice, but you can often run larger units in a lower and quieter environment. In contrast, smaller machines in large homes have to operate at a higher speed. Unfortunately, this usually means more sound.


The filter is what effectively makes the machine do the job. If the filter is of poor quality or simply does not have enough filtration stages, the air will not be cleaned from dust particles, smoke, allergens and odors. The best filters to look for are HEPA and activated carbon.

HEPA filters remove the very small pollutants in the atmosphere. Pollutants that HEPA filters can remove are dust, dust mites, pollen and mold.

However, for odors, you need an activated carbon filter. These can collect chemicals, gas molecules, formaldehyde, and more, in addition to odors.

Fortunately, most whole house air purifiers use both. The downside, however, is that they eventually require replacement, which is expensive. For comparison, an average filter replacements are $30 per piece.


Warranties allow you to replace defective components or even the entire unit if something fails. When manufacturers put a warranty on their products, it usually means they know their product works. Therefore, a great product usually means that the product is worth its price. Avoid air purifiers that do not have any warranty period.
