Membrane Solutions MSA3 Air Purifier for Home, Room Up to 1590 sq ft. H13 True HEPA Filter Air Purifier for Bedroom 22db, 100% Ozone Free Air Cleaner for Smoke, Pet Odor, Dust

I am genuinely impressed with the Membrane Solutions . From the moment I plugged it in, I could feel the difference. The air in my home feels fresher, lighter, and cleaner especially in the bedroom. I suffer from allergies and have pets, and this purifier has helped so much. I wake up without congestion now, and the pet smell is completely gone. The H13 True HEPA filter is powerful. It really does remove dust, smoke, and allergens I notice way less dust on my furniture. It also covers a huge space (up to 1590 sq ft), which is great for open rooms or apartments. Even running all day, it stays super quiet… the 22dB sleep mode is honestly barely noticeable. I also appreciate that it’s 100% ozone free and safe for kids and pets. The design is sleek, modern, and easy to move around. The controls are simple, the filter is easy to replace, and the performance is consistent. If you’re looking for a purifier that actually works and makes a noticeable difference in air quality, this is absolutely worth it. I’d buy it again without hesitation! Lovely clean color.

This is the third Membrane Solutions MSA3 air purifier I have purchased, not because of any problems. I just wanted another one to put in the back bedroom that the dogs sleep in. The other two do a great job and I wanted to get a jump on the hair and slight odor in the other room. The units are wells made and there are three normal speeds to chose from and a sleep mode that is very quiet with no lights on so it is hardly noticeable even when running right next to the bed. Replacement filters are fairly expensive but they remove a lot o pet hair and other debris from the air. The first filter comes in the machine sealed in a plastic bag, so don't forget to remove the from panel and take the bag of the filter and reinstall it or the purifier will never start working. Removing the front cover is easy and it snaps back in place when properly adjusted.

Update 2: I found less expensive replacement filter cartridges that work without modification. It seems the cartridges might work on a timer basis with replacement about every 3 or 4 months as indicated by the unit lights. The replacement filter was down to 1/4 as per light indicator. I pushed the reset button for about 5 seconds and the light indicator is now reading like it was new. I will monitor the operation thru dust accumulation on furniture. If I lived in a very active home, I could understand the fast depletion of the cartridge. That is not the case. I am wondering if most manufacturers of household units and their cartridges also work on the timer basis per operational hours and not actual air quality? I guess this is a question for manufacturers of both the unit and cartridges. I saved the original filter and wonder if the same will happen UPDATE: My house is not high traffic and I only have 1 small dog that does not shed. I do the regular, not over the top vacuuming of the floor and furniture. I have not done any frying or heavy cooking. The filter is only 2 months old and is down to one quarter of life left. Knowing that an air filter is just a fan and filter, my next purchase will be a less expensive brand with cheaper and maybe universal type filter. I have noticed less dust on the furniture and electronics (dust magnets!) but think smaller units, with strategic placement might do the job as well. I still compliment the manufacturer for making a good product, but filter cartridge life is no where near what is advertised. I purchased the smart model, my dumb move as it was impossible to pair with my Android phone even after Customer service and I tried every workaround. I was refunded the difference in price. The customer service was honest in telling me there was no difference in the units. I have been running it on Auto since my purchase about a month ago. I hesitated reviewing until I saw if it made a difference in dust and if it actually covered the square footage as advertised. It has made a difference in dust and helps eliminate cooking odors that linger. It is very quiet even on high fan. The indicator seems to be accurate turning from green to yellow to red as air quality diminishes and changes back to green. You can notice the difference in the air smells. Since the coverage area in less than stated, I will be purchasing another to put in the larger master bedroom. Bottom line, don't look for miracles. Make sure you dust and vacuum before your initial startup. Unfortunately it won't suck the dust off or out of furniture; you have to do that yourself. Since I'm purchasing another, that's testimony enough to the fact that this air purifier does help. The filter cartridges are not expensive and seem to last. Remember, as in all air purifiers, they are just fans and filters.

We really love this air cleaner for our apartment. It picks up all sorts of dust in the living room and you can see the filters are doing their job. Various settings for low to rapid clean--all appreciated and quieter than our other units in the home. When we had a problem, Ellen from Customer Service was right on the case, first giving us advice from thier technician on how to address the issue and then when it could not be fixed, the company sent a new one in the mail to us. Really above and beyond the usual CS at most companies. Thank you Ellen and Membrane Solutions!

Love this air purifier. Very durable, controls smells and dust well. Highest setting is noisy but the other two settings are fairly quiet. Can turn off the lights and lock the settings. Easy to replace the filters. Great value.

Love this air purifier! Air smells clean, eliminates odors, no noise, great price

My second purchase of same item in past couple of year's Does a great job to purify the air and with dog and cat. It makes my home odor free. Also, keeps our allergies minimum and I am never sick. I keep one my daughter s bedroom she has a high ceiling and a shag carpet. I know this helps breathing. .

Originally gave this three stars but have now am giving it 5 stars because of their customer service. After my review was posted their customer service contacted me and offered to replace the unit. The new unit showed up within the week and is nice and quiet. It's nice to see a seller that stands behind their products. When I first got this air purifier it worked fantastic. It removed cooking odors better than any other purifier we have ever had and removed so much more airborne dust as well. Now just 3 months out of warranty it has developed a chirping or squeaking noise coming from the fan. If I turn the fan up to high and run it at that speed for five minutes or so then set it back to auto it slows it down to the lowest fan setting and the squeaking begins again. We're at the point where we only run it when we are at work because the sound is just to annoying to have in the background while trying to watch television. I bought a different model of the same brand for my bedroom and as of yet I have had no issues with it but I'm a bit concerned as to it's longevity. Only time will tell if I need to replace it as well but I am really disappointed with this model.
