DUMOS Air Purifier Replacement Filter for Bedroom, H13 True HEPA 3-in-1 Filter, 1200 Sq.ft Room Capacity, White, Single Pack

This air purifier is great especially for the price. I bought one that was twice the price and has the same features. it has a ring on top of it that will indicate the severity of your air quality. For example red is for severe and then it goes blue for middle and then green is good and it cleans the air pretty quick as far as the noise level that's pretty great also. It came with 3 filters so I cannot imagine getting a better deal anywhere

As show in the picture. Bigger size than other brands. Make sure to buy a extra filter because when you look for individual filter is hard to find. NOT noise and easy to use.

The DUMOS Air Purifier with H13 HEPA filter works great! It noticeably improved my air quality within a day—less dust, fewer allergy symptoms, and fresher air. It's super quiet and Sleek design, easy to use, and a great value for the price. Highly recommend!

This is a nice size air purifier. I've only used it for a couple of days, but it seems to be working well. The only real complaint is the instructions should say to plug the unit in to see and operate the control panel. I'm sure I should have known but the button that is the control panel doesn't seem large enough to be a control panel. Wel'll see how well it removes dust and other particles common to inside home.

Large cylindrical filter. Quiet 3 speed fan. We run Speed 2 at night, and it does not disturb our sleep. Cleans the air nicely. However, we used this 3 months, and the filter looks almost new. But, I don't know how to get replacement filters when we need them in the future.

Very noisy on the high setting but quiet on the sleep setting. The sleep setting is slow fan, minimum flow. My favorite part of this particular system. Looks like that's what I will use while I am around it. I can turn it up when I leave the room. Very happy with this. Thank you.

This air purifier is decent overall. It's very quiet on low and medium settings, which is great for daily use. However, the high setting is too noisy for my liking—I only use it for short periods when I'm cleaning. After two weeks, I checked the filter and was surprised to see minimal dust collection. Given how dusty my home usually is, I expected more. I'll give it another month to see if it's just a fluke or if the purifier isn't capturing as much as I'd hoped

I have bad allergies and thought an air purifier might help in my bedroom. I turned on high for a couple of nights and now just leave on auto. If the air quality changes it will turn up. I was so happy with this that I bought a second one for my family room. I really do notice a difference and am very happy with this product! I have recommended it to two people who have also purchased one and are very pleased.

At first, I was hesitant to buy this air purifier, wondering if it would really make a difference. But after a few weeks of use, I have to say I'm impressed! I have seasonal allergies and often wake up with a stuffy nose, but since using this, my congestion has noticeably improved. It runs quietly, especially in sleep mode, and I wake up feeling much more refreshed. Definitely worth it—highly recommend for anyone with allergies or sinus issues!

I've been using this air purifier in my bedroom for a few weeks, and it's incredibly quiet—even on medium, it's barely noticeable. The sleep mode is a great feature; it dims the lights and runs at a whisper-quiet level, which has really helped improve my sleep quality. I used to wake up feeling stuffy, but now I breathe much easier in the mornings. If you're looking for something silent and effective for nighttime use, this is a great choice!
