I’ve been using the PuroAir 400 replacement filter for a while now, and it continues to impress. The replacement process is quick and hassle-free it fits perfectly in the unit every time. I noticed an immediate improvement in air quality after installing it, just like with the original. It does a great job capturing dust, pet dander, and other allergens, which is important for our household,I have 4 kids and 2 dogs. The filter also lasts as advertised, making it a dependable and worthwhile purchase. If you have the PuroAir 400, this filter is a must to keep things running smoothly. Highly recommend!
