300/300S Replacement Filter for Coway AIRMEGA Max2 300/300S Air Purifie-r, Combined with HEPA and Activated Carbon 2-in-1 Filter, AP-1515-FP

These filters are excellent. I replace them every 6 months to 1 year or so. You can save some considerable money by using the filters here as opposed to the original Coway ones. The filters have a nice gasket around them, which gives them a more snug fit. I have noticed no issues or differences since using these filters since 2021. Well worth it!

Using this in a Coway Airmega 300 and it fits perfectly. Comparing this to the original, this is a little lighter when holding each one. I suspect with the price being half of the cost of the OEM that some parts will be affected. Seems to be built the same in terms of layers and design. For half off the OEM, I'm willing to give up some density in material to still filter out a good amount of whatever is in the air.

We bought these replacement filters for our two Coway Airmega 300S units, and for the price (two sets), they’re a great deal compared to the original Coway filters. Installation was simple—just swap out the old filter and reset the indicator. They fit perfectly and our machines recognized them without any issues. Side-by-side with the original Coway filter, we did notice a difference in the carbon design. The OEM version has slightly larger cylindrical charcoal pieces arranged in hexagons, while this replacement uses smaller cylindrical charcoal pieces arranged in circular sections. That said, there’s still plenty of carbon in the filter, and performance has been great so far. We’re happy with them—they work well in our units and keep the air fresh. If you’re looking to save some money without sacrificing compatibility, these are a solid option.

Well great price for filters, quality ok for Chinese manufacturing.

Love these! They work great. If I were to purchase these from Conway Airmega, the company that makes the air filter I have, they would be over $100 for a set of 2. Here on Amazon they are a fraction of the price. Everything about them is identical to the machine original.

These fit the coway airmega 300 perfectly. Great value.

They work as well as the original filter.

I bought this for my 300s and have no complaints. The fit was a little tighter than OEM, had to squeeze it in. No weird smells, quality seems to be on par with OEM, and air filter works like usual. My change filter light went off after only 6 months with the OEM filter, so I feel better buying these if I need to change that often.

Worked well with my coway air filter

The part is for the airmega 400/400S. Description says 300/300S. Also the quality of the frame / construction is inferior to the original part. This may not affect performance, but given it’s much less expensive than the OEM part.
