AIRMEGA Max 2 Air Purifier Replacement Filter Set for 300/300S

I had no issues replacing the filter on my Coway. I liked that the filter fit perfectly and is exactly like the one that came with the machine. I haven't replaced it in a year and a half of having the machine (my first Coway) and the light just came on to replace the filter. I've been regularly cleaning the mesh filter every time that light goes on. You press and hold the lit Wash icon to reset the special timer on the Wash lights. Pros to using this replacement: It doesn't void the warranty on the machine. It is fully tested with the machine so you know it won't damage it. It is clearly the same item so you know the quality and can compare the old one with the new one and see it really is kind of worn after a year and half of working. I know it fits and no air is getting through the filter on the sides, like I saw happens for some third party filters. Cons to using this replacement: It is very expensive! If you are replacing this more often than I am, it is going to cost a lot. I was going to buy a cheaper option, but when I thought about how expensive the machine was to begin with, I figured why would I go with a cheaper filter now and make that whole purchase pointless?! Just my thoughts anyway!

These coway units work great and they have good, available filters

these filters are amazing and super easy to use. Right on the filter it tells you which is the correct way to place it in the air purifier. They do not smell like plastic.

Easy to swap out and these filters do a great job and last well. We replace them twice/year.

I completely renovated my condo a year and a half ago and the dust was horrendous so naturally I blew through the first filter set in about 6 months...eek. Anyways, when I ordered this filter I was happy to see that the quality was just as good as the first and the price was much nicer than what I could find elsewhere online. It has now been almost a year since I bought the replacement filter and it's still chugging along so good to know I won't have to replace them every 6 months!! The airmega has been a life saver (less allergies and dust)! Also ignore the dustiness in the pic, it's due to be cleaned out (pro tip: hand vac your carbon filter when you clean out the mesh filter in order to get a longer life out of it).
