300/300S Replacement Filter for Coway AIRMEGA Max2 300/300S Air Purifie-r

Probably the fifth or sixth time we have purchased these purifiers. They are great, easy to clean and last almost a year if taken care of properly. Excellent buy and very easy to install and clean. Highly recommend.

I am extremely happy with these replacement filters for my son’s Conway AIRMEGA Max2 Air Purifier. He has severe asthma and has to have the purifier running 24/7. These filters will allow us to replace them more frequently. Installation was fast and easy. They fit in perfectly and look almost identical. They seem very durable and the material like charcoal differs very slightly. They are doing exactly what they are designed to do. Keep the air purified and clean to keep his room allergy free. I will definitely be purchasing these on a regular basis. I highly recommend them to anyone who has AIRMEGA purifier that takes these filters. ⭐️⭐️⭐️⭐️⭐️ experience.

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.

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.

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

Running these in both a 300 and a 300S and honestly can't tell a difference from the originals. If anything, air quality readings seem just as good, maybe better. At this price compared to Coway's official filters, it's not even a close call. No fitment issues, no weird smell out of the box, just works. If you've been paying full OEM price out of brand loyalty, stop. These do the job for way less.

These fit the coway airmega 300 perfectly. Great value.

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.
