Ok

Quick delivery, good quality and price

Not sure how to tell if it's working or not but I didn't need to take hayfever medication (unless I went outside) throughout August. I have a lot of house plants (mostly without flowers) and I haven't vacuumed recently so I'm guessing it's doing its job.

Exactly what I was looking for

Original fit. Excellent filter. I vacuum white side of filter every two months due to lots of foot traffic in room. Collects dust 100%. I change to new ones everyk 6 months.

I've ordered MA-15 filters before that ended up being fake filled with cardboard. These are the real hepa filters. They work amazingly well, we live in a condo along a hwy and get a lot of dust, these have helped, decreasing our dusting from almost daily to every other week.

Great filters. They do an excellent job for what I need, which is a musty basement and a room with a pet bird. I love that these catch the super fine bird dander that was making my allergies act up. The room does seem fresher, too. They're a snug fit in the unit, but easy to install and remove. They last as long as they claim to. I do think they're on the expensive side, but they live up to their claims.

Fit perfectly! Easy to replace and was greatful they came in a sturdy package to prevent damage
