Benefits of using an air purifier equipped with a HEPA filter
You may have noticed that we have put a lot of emphasis on the use of HEPA filter and deliberately picked air purifiers equipped with a HEPA filter alongside other filters.
HEPA denotes High-Efficiency Particulate Air. It is an indication that an air purifier has fulfilled the efficiency level specifications set by the United States Department of Energy.
These standards indicate that an air purifier needs to have the capacity to get rid of 99% of air particulates or higher. The whole purpose of using an air purifier is to get rid of all allergens where possible. For example, there are air purifiers that help to eliminate mold and mildew.
Allergens like mold, pollen, pet hair, dust mites, cat litter, bacteria, and viruses could easily escape other filters but a HEPA filter has been proven to eliminate them.
The particles could be as small as 0.3 microns and can be airborne or harbored in area rugs, carpets, furniture, drapes, and curtains.
Other ways of getting rid of cat litter odor
- Frequent cleaning of bedding, carpets, pet habitats, and rugs
- Vacuuming furniture often especially if pets climb on them
- Keep pets outside the living area especially if you are allergic
- Finally, if allergies persist, replace carpets with hard floors
