CP3 2 Universal Ozone Plates Made in USA Inc. 4.5" x 4.5" for Fresh Air EcoQuest Alpine Vollara GreenTech Spring Air Natures Air

Plates were exactly the same size as the ones that came with my purifier... but the glue they used to attach the metal mesh to the ceramic plate was bulging out on all the edges (they applied too much glue?). It was very difficult to insert the plates because the glue was sticking out. Didn't feel like sending them back and waiting for a new order, so I used a razor blade to cut down the excess glue at the edges so that I could slide the plates into my machine. Wish the company had checked the plates before packing them. Quality control thing. Otherwise, they are working fine.

I was nervous about buying these plates after reading the first review. Well my plates came today and looked great! I pulled out the original plates made by the manufactuter and they were covered with glue oozing out on all sides! The quality of the plates I got today was far superior to the $50 plates! I put in both plates and they really put out the ozone, so I am cutting back to one plate to see if that will be sufficient. Don't be afraid to purchase these!

These didn't even last 2 months. They came off on both sides after I ran them under warm water. Simple hot glue used to affix plates. I tried to reattach but Metal part affixed to the plate but to no avail. The metal part is also smaller than the once that came with the ozone machine I have- those lasted almost a year & a half.

They worked great until I washed them in warm water and amonia per instructions. ALL THE SCREENS FELL OFF! I glued them back on and now they barely give off any O3. Thanks for selling junk. Only one month old.

it’s unfortunate for a company in the United States but they fell apart after their first cleaning stay away from them

This plate was far superior to my original manufacture plate. Once installed my air purifier was preforming like new again. The quality of constrution was evident from the time I unboxed them.

I bought these ozone plates and was able to use one time. Once cleaned in ammonia they come apart and are trash.

I originally rated this a 1 star because when I washed it the first time the screen came off. Since then the sell has sent me new ones free of charge and they are working fine.
