Great product
We just received our air purifier today. It was ordered on April 16, 2021 and was received 7 days later. We purchased it based on the information about the machine as well as the fact that it uses a HEPA 13 air filter which is supposed to be better than the HEPA filter. It was easy to remove the filter and remove the protective film and placing it back in the machine. It has a few buttons that are clearly marked and, when necessary, it will notify us when we need to replace the filter - no guessing or keeping track of when to replace it. It should be replaced at least once every six months, or after 3,000 hours, whichever comes first. It has several speeds so that you can set it for your needs. And it is small enough that we can move it from the living room to the bedroom when desired to clean the air in other parts of the house. We have only had it in use for a few hours, but we can tell the difference already. The company also has a program where you can have them send another filter at a designated time (1 every month up to 1 every 6 months.

Wish I had purchased one sooner!
So far, I am very happy with the MA-40 Air Purifier. I do not find it excessively loud on the sleep cycle at night and it really keeps the air in my room fresh. I would buy again. The unit arrived intact and protected. Shipping was good!
this works amazing for pet owners
I've had allergies for the past three years ever since I moved into this new house it's very large and no matter how much I dust I can still smell a cat that the previous owner had along with allergies from the four dogs I own my downstairs always smelled like dogs because I have four large large dogs and we would always be down there I bought this metaphase air purifier because the last one I bought for $100 didn't do any didn't help me at all and I was reluctant to spend so much money on an air purifier but it's something I've needed for years I got this and put it downstairs in with an hour that dog smell was all gone it's probably about 1200 ft.² downstairs I had it upstairs and Let it run for an hour or two and I can immediately feel the difference I read reviews and it seemed like they were fake people leaving reviews when they said that they noticed a change in the air quality so quickly I do agree with them I've never had an air purifier work so well I bought this on Black Friday for sale and use the coupon code online so it was only $216 it also comes with a lifetime warranty which really brought me to it you just have to make sure you replace the filter every six months I've checked out my filter and I can already see that it's starting to turn brown from the dirt in the air which is amazing That is pulling so much dirt from the air so quickly and disgusting at the same time to know that this much dirt was in my air I highly recommend this and I will probably buy another unit next year so I don't have to move this one up and down the steps or wherever I go but she can no longer tell I have dogs in this house he doesn't smell like dogs at all which is crazy when you have four large dogs
