Air filter
This air filter is amazing. It efficiently helps with every-day maintenance (we have two dogs), and also those times when we accidentally burn something in the oven and fill the house with smoke - it’s so quick and does an excellent job. Great for fire season, too. So reliable for a clean-air home (we live in Northern California).

Excellent purifying
Been using the air purifier #121 with the automatic shipping of the filter for about 2 years. The unit is a bit noisy and the filters are expensive. That said I like the unit. I also use the nylon sleeve with the unit and wash it bi-monthly it's very dusty where I live and I appreciate that this unit really does work well. It helps with dust and odors. People comment that my house smells so fresh. 4 out of 5 stars because of the price and noise but give 5 stars for excellent purifying.

Noisy
The device has started making noticeable noise. Previously, it operated silently to the point where its presence was barely detectable, but recently, it has begun emitting louder sounds, indicating a change in its functioning. It's been 4 years old.
