What Our Customers Have to Say
Frequently Asked Questions
What are the benefits of a portable air filter?
Portable room filters are relatively inexpensive and can be moved from room-to-room. Portable air purifiers provide a perfect clean air solution for offices, bedrooms, nurseries, and family rooms. Your whole house heating and cooling system may offer substandard air filtration or none at all – so adding a portable air filter to any room is a perfect way to ensure robust indoor air quality in commonly occupied spaces.
Does my portable air filter have a HEPA filter?
Probably. Most portable air filters have a HEPA component. In other words - a filter that removes 99.97% of airborne particles. Check the specifications sheet for your air filter system - but the vast majority of these systems do carry HEPA filtration claims.
How often should I replace the filter in my room air cleaner?
If you operate your portable air filter continuously - the main HEPA filter should be changed every 90 days. Under normal use - portable HEPA filters can last up to 6 months. If the system includes a separate pre-filter, it should be changed every month.
What is a multi-stage portable air filter?
Many manufacturers will include multiple stages of filtration in their product. For example, there may be a stage 1 prefilter with an activated carbon component. This pre filter will reduce odors and VOCs – and extend the life of the main HEPA filter by capturing very large particles. If the prefilter does not include activated carbon – another stage 3 filter with carbon may be present. Some manufacturers will include all 3 stages in 1 filter.
Can a room air filter help with allergies?
Yes. A room air filter, especially one with a HEPA filter, can help reduce airborne allergens such as pollen, pet dander, and dust mites within a single room.
Do room air filters remove odors?
Some room air filters include activated carbon layers that help reduce odors from cooking, pets, smoke, or household chemicals. Odor reduction depends on the filter type and purifier design.
Is one room air filter enough for an entire house?
No. Room air filters are designed to clean air in individual rooms or enclosed spaces. For whole-home coverage, multiple units or a whole-house air filtration system is typically required.
How do I know which room air filter fits my air purifier?
The easiest way is to search by model number or brand using the filter finder on this page. This ensures the replacement filter matches your air purifier correctly.
Do room air filters help with smoke or wildfire air?
Yes. High-efficiency room air filters, particularly HEPA filters, can help reduce fine particles found in smoke. Filters with carbon layers are especially helpful for odor reduction.
