Coway Airmega 250/250S Air Purifier Replacement Filter Set, Max 2 HEPA Filter and Active Carbon Filter, AP-1720-FP

Wouldn't say I look forward to buying these filters due to the cost, that being said these genuine units last a looooong time and I would not want to cheap out. These are as good as any high-end 3m filter in terms of construction and have a huge amount of surface area. The activated carbon still seems to work after running 24/7 for a year or more.

It is pricey however it made my home smell clean. The quality is great. It fit right in with no problem.

Very effective as clearing smoke and odors

Filter is the name brand and matches the old one perfectly.

item received, appears to be a genuine part and well made, however, please be advised that this is shipped as a single filter. This item page is ambiguous and suggests you are receiving a two pack when you are not. this needs to be updated to avoid confusing more people.

Exceptional quality, energy efficient unit at a fair price. Works exceptionally well with severe allergies. Indeed it does an excellent job. Bonnie

Original filters always work the best, but cost some $$

When you invest in an air filter you need to be prepared to pay the money for the correct brand specific filter! Why would you spend the money on the machine and then short its working capability by getting a generic and less effective filter! The amount of crap this filter removed in its year of working is incredible. I just feel better having it running!
