Works well
Now that I’m using my air purifiers 24x7, I’m noticing much less dust

Love the Allergen Blocker
We have 2 Blue Pure 411 series air purifiers at home and once the Allergenblocker filter came on the market, we purchased them and have been experiencing a much better and pronounced cleaner air - it kicks in immediately when you sear shishito peppers on your stove top; it kicks in when there’s a dust storm outside; or when your dog is running by. The sound is next to nothing as well. Very easy to maintain every 6 months, we get alerted to needing a new filter. Recommend this product 100%.

411 Allergenblock Filter works
During the recent fire smoke on the US east coast, these filters were particularly helpful.

Keeps getting lower quality
Won't we have owned our products for multiple years and feel that the replacement filters are becoming more and more value designed. The materials seem lower quality from when we first purchased our air filters. Specifically the activated charcoal foam is less dense and less thick over the years. We like your product but please revert back to quality materials.

Thank you very much for sharing your feedback with us. We sincerely apologize for the inconvenience you are experiencing with the filter quality. Over the years, we have continuously improved our filter materials by adopting highly porous, advanced carbon structures instead of the traditional heavier and denser carbon barriers. These enhancements are designed to provide better performance and efficiency. Our dedicated support team will be reaching out to you shortly to assist you further and address any concerns you may have.

Great filter
This is quiet and efficient and the filter catches the pollen and dust. Super pleased.
