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.
