Understandably, whether or not air purifiers actually work is the first question people ask. Before getting into details, the main thing you should know is that an air purifier alone is not an adequate solution to allergy or indoor pollutant issues. It should be used in conjunction with regular cleaning, dusting, mopping, disinfecting, etc.

The general consensus is that air purifiers do actually clean the air you breathe. One issue will hear about is the fact that Ionizers –a type of air purifier—are ineffective because they simply make airborne particles stick to walls or drop to the floor. This means that they don’t actually rid your home of the things that cause allergies or nasal discomfort. Furthermore, these machines produce ozone, which is a lung irritant.

People looking for information about how to get rid of dust or other allergens will be discouraged by this information. Still, you should know that Ionizers are not the recommended type of air purifier. I recommend the use of a machine that uses a HEPA filter, which is a high-efficiency filter that will actually trap these particles. You can then clean the filter and actually remove the substances from your home.

HEPA filters have been around for decades, and, to be classified as authentic HEPA, they must be able to remove over 99.9% of particles larger than 0.3 microns in size. For comparison, most research has suggested that the average size of a household dust particle is 0.5 to several microns in size, while mold spores and pollen are greater than 10. Tobacco smoke and other odor particles have been found to come in sizes on either side of this .3 micron threshold, and there is a special filter for these particles that are used in conjunction with HEPA filters: activated carbon filters.

But my experience with this cute air purifier:

Compact enough to fit on your desk but powerful enough to remove 99.9 percent of dust, pollen, smoke, odor, mold spores, and pet dander, the TREDY Air Purifier is an excellent entry-level option. Rather than using a UV or ions to clean the air, the device features a 4-Stage True HEPA Filter. This comprises a pre-filter, a HEPA filter, an activated carbon filter, and a protective net filter. Three fan settings let you control the speed and volume of the purifier.

This air purifier is definitely designed for use in the bedroom, but I can also tuck it into the corner of my desk at work. It features a soft optional night light with two brightness settings as well as a very quiet fan. It’s not out of place on your nightstand, with its white or black case and sleek design.
Overall, this air purifier is better suited to small rooms than large homes and does the job well.
