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.

So quiet and troublefree
The things I love about the 2 air purifiers that I have is that they are whisper quiet and I haven't had any performance issues since I've owned them, which is going on 7 years. I have to change the filters about every 6 months because I run them 24/7 on low speed. I'm gonna hate the day I have to replace them, whenever that comes.

Great product buttttttt…We all knew what the filters cost or should have. But yikes - like so many other products with such parts, the profit are made by the boatload 🛶 in the periodic expendable disposable parts- and we quickly spend more on the parts than the products themselves- but we are all ready fish on the hook- 🪝 🐠🐠
