Medify MA-25 Air Purifier with True HEPA H13 Filter | 825 ft² Coverage in 1hr for Allergens, Smoke, Wildfires, Odors, Pollen, Pet Dander | Removal to 0.1 Microns | White, 1-Pack

It works well, removes dust and smell efficiently. It's quiet in low and medium mode. Its noisy at high mode, but I only need to keep at that level for few minutes when cooking something that smells or smokes. The timer works well, although the 4-hour timer light failed after a year in my device.The filter lasts for at least 1 year, which is good enough considering the device is in the kitchen, where grease can clog the filter (but I don't fry food at home, so not much grease).The only issue that one might have is that the air is pushed out straight to the front of the device, but I'd prefer to be able to change the airflow direction up. I improvised by tilting the device up a bit.

Easy to set up, quiet, and effective as I have not been waking up with a stuffy nose.

I am very happy with my Medify purifiers. I did a lot of comparative research and chose these based on particle level filtration (.1 microns HEPA,) speed and ionization options, efficiency, and price. I have 3 of them, 1 large and 2 small. They are very effective at removing odors and particulates quickly. This size can clean the air in a small room within 2-3 minutes or freshen an open floor plan living-dining-kitchen area in 5-10. I love the easy touch digital control panel, and the sleep option so I can eliminate blue light display at night. It’s definitely helped with my allergies and mold sensitivities, including in some questionable, mold-exposed places.

This is a good air filter.I'd purchased one for my bedroom, and even running at the low setting, it noticeably cleans the air. There are a few quirks that could have been done better, but rather than trying a different filter (and needing to buy two different sets of replacement filter elements) I'd bought a second one for my living room.The good: It's quiet, it's easy to use, it's lightweight, the visual design is pretty, and it fits in my space – almost.The quirks:The power cord plugs in the back, which means that the unit can't be placed next to a wall. It has to be about 2 inches away from the wall. The sides and the front can't go next to a wall either because that's where the air vents are.The control panel is on the top. There is space on the front where the control panel could go, but it's on the top. Unfortunately, this means that you can't put anything on top of the unit. It's the perfect size to put down a book you're reading on, but you can't. Also, good luck explaining to your cat or bird that they cannot perch on top of the unit..The indicators are integral to the control buttons, not adjacent to them, this means that you cannot blackout the indicator lights with black tape without interfering with the controls. There is a button to dim the controls, but that button also glows, but it is significantly dimmer than the other buttons. However, if the unit is off, the power button flashes, and the dim functionality does not work.In my bedroom I find the dim function sufficiently dim, and the fan quiet enough to sleep nearby, but if I want to turn it off when sleeping, I need to unplug the cord to turn of the flashing power button, and that's annoying.But again, it's a good air filter, and despite the quirks, it's good enough for me to buy a second one.

We live in a big city so air purifiers to help reduce air particles / dust are important. We also have 2 cats and 2 kids and a good friend with a cat allergy so need something that works well. We bought this unit for our living/dining/kitchen area which is just about 1000sf. Out of the box, this unit was super easy to get started and immediately began clearing the air - the sun was shining through the window so we could literally see the dust flow towards the unit's 2 filters!Here are the PROS IMO:1. Filters are super easy to clean and change - the covers easily pinch to pull off (though would not be easy for a small kid to do) and the filers have a tab to pull out. I vacuum the layer of dust that collect on the outside of the filter, then change every 6-12 months). The outer cover can also easily be cleaned with plain soap and water since it is 100% removable.2. Sound / speeds - there are 3 speeds on this unit. The first level is almost totally silent yet you can still feel a slight breeze from the output. the second is what I would describe as a light fan sound. The third speed is definitely louder and output stronger so we use it when cooking / cleaning or need to purify the entire room quickly for guests. What I do like about the 3rd setting is that it creates a good "white noise" for sleeping and drowns out "city noise" and other background noise.3. Portable - this unit is light weight and easy to carry from room to room. We transfer it to the kids rooms when they have friends over then back to the kitchen area when cooking, then to the bedroom at night.4. Cost - this was less expensive than many other comparable units that cover large rooms5. Style - this has a nice, clean, modern style that can blend into any room.CONSwell, none yet! If there was an additional feature I would like to see it would be a sensor of just how clean the air is.I highly recommend this unit!
