MORENTO 2 Pack HY4866 Genuine Air Purifier Replacement Filter for HY4866 Air Purifier, Enhanced Version

This filter literally catches everything in my air.I had doubts how dirty environment was until I looked at the filter two weeks later and WOW.

These fit the air filter I bought perfectly, and it does a fantastic job of filtering the air in my bedroom, helping with my allergies. The filters seem to last forever before they have to be replaced.

This filter works great. My old filter was extremely dirty. I had put a new one, and it catches alot of dust.

This air filter is great for medium sized spaces. The noise level is dependent on the intensity of filtering you like. When my wife is cooking, I turn the air filter on to the highest level (4F) and the food order is gone in about 30 minutes. I live in a 1200 sq foot home so I move the filter between 2 sides of my home. My wife is terribly allergic to pollen. This air filter has been a life saver this spring. The sleep mode is excellent. Sometimes, I forgot that the air filter is on during the middle of the night.

Usually the Morento HY4866 works quietly on the automatic fan setting. If I should smell up the house by frying in the kitchen, the PM2.5 sensor on the purifier will jump from about 10 to 150. It is located forty feet away from the stove and the fan kicks up to high. It will run on a gradually slowing fan speed for a little over an hour until the PM2.5 reading is under 20. It detected and cleaned air from outdoor grilling once when it was positioned by the door. It was winter and the door was opened only to monitor the cooking.

Crazy price for a air filter but you need it.UPDATE: I went to purchase another filter and the seller had raised the price by $15.00 in two months.What greed.

Great size. Easy to use. Effective.
