Are Cheap Air Purifiers Worth it?

Yes, cheap air purifiers are generally worth it unless they emit ozone. Avoid these devices as they can be harmful to your health.

There are many air purifiers under $100 that are efficient and powerful for use in your homes.

Below we explore 3 features to look for when you are consider a cheap air purifier.

Top Features to Look for Air Purifiers Under $100

1. Multistage Filtration System

One of the most common ways for manufacturers to design inexpensive air purifiers is to use a single stage air filtration system.

These devices would be cheap but not as effective.

It is important to look for is a multistage filtration system. This design combines several types of air filters and provides the most protection against harmful airborne pollutants.

A multi-stage air purifier gives you the most value.

Multi-stage air filter options include:

  • Pre-filter – This collects the biggest particles like hair, pet hair and dust which helps to extend the life of the filters.
  • HEPA Filter – True HEPA filters can remove and  trap up to 99.97% of microscopic allergens like pollen, fine dust, pet dander, and mold spores.
  • Activated Carbon Filter – This highly absorbent filter is great at removing household odors, smoke, and airborne chemicals.
  • Ionizer – releases negative ions that bind to airborne particles making them easier to remove
  • UV Light – kills bacteria and viruses by destroying the DNA structure

As you’ll see in the recommended products section below, the #1 cheap air purifier includes a combination of these features

2. Frequency of Filter Replacements

Some cheap air purifiers are actually costly as they require frequent filter replacements. When you are buying an air purifier always check the product description to see the frequency of filter replacements.

3. Maximum Room Coverage

The last aspect to consider is the maximum room coverage. You may be wasting your money if the air purifier is unable to handle the room size you’ve placed it in.

To determine what size area the product must meet, measure the square footage of the room.

Take a measuring tape or app and multiply the width by the length. For example, a 12′ x 12′ room = 144 sq. ft.

In this example you’ll need an air purifier with a room coverage of at least 144.

Now that you know the 3 features to look for, check out our guide below to find our recommendations on the best cheap and affordable air purifiers.
