These filters fit perfectly and there is absolutely no difference between them and the originals. I’ve had this early model Dyson since 2011 and these filters help keep it running great and the price cannot be beat! Thank You Discount Filters!

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.
