🌬️ My Happi Air Purifier: True HEPA H13 Filter with UV & Active Carbon - 5-in-1 Layers, LED Air Particle Sensor Display, Self-Cleaning, Whisper Quiet - 3 Speeds, 500 Sq. Ft Coverage (White) Review

I bought this for use in a van, primarily for a charcoal filter stage to remove chemicals so I was looking for something small, quiet and effective. It's very intuitive and the controls work well. It's also pretty quiet on low settings. I'm not exactly sure, but I suspect it uses a brushless fan motor, so it might be a bit more expensive than similar models. I was happy to pay a little more for a quieter and more efficient fan. At low speed, it consumes only about 3 watts. It's been on all the…

This may be a good air purifier but if you don't know how to use it and what it does then it's a waste of money. The instructions are sparse and do not answer the manufacturer's questions. Plug it in and the lights come on, the numbers flash and the colors change, but you know as well as I do what it does. I think if you're an electrical or air quality engineer you might have some idea of whether or not it's doing something. A question was asked as to why the numeric display always counts 1, 2,

...in the woods of the American West, an air purifier is all the more important. Here's what my sister-in-law thinks: First impressions of this air filter were that it's sleek and quiet, allowing it to be placed in a living space without being too obtrusive. The setup is very easy and intuitive. It has an automatic mode that starts at a higher setting and automatically adjusts as air quality improves. A small LED screen displays this air quality, but without an alternative measuring tool it is…

This little air filter is very effective! I was a bit skeptical at first because there is a big gap around the filter when you put it in. All HEPA filters I've ever had fit snugly in the filter compartment, but this one didn't. I installed it in my office as it is designed for small spaces. If food odors ever get inside, the filter will adapt and quickly kick in to demonstrate how it's filtering the air. The lower the number, the better the air quality. It's incredibly quiet even at its lowest…

I use this in the bedroom. I sleep on one side of the large bed (dogs sleep on the other side). My Happi is on the bedside table on the other side of the bed. So about three or four meters away. I run it automatically. I do not hear anything. I don't use night mode, I don't see a need for it. Very, very calm. If I stand next to him and get very quiet, I can hardly hear him. The UV light is weak - you can see a very faint glow coming from within - nothing to disturb my sleep. The sensor on the…

This 8" x 12" small air purifier from Happi is super easy to install and use so with just 3 simple steps you don't have to worry about reading the manual or anything else . Keys. The ON/OFF button is in the middle, the UV ON/OFF lamp is on the right (as viewed from the front) and the fan speed knob is on the left. There are three fan speeds: one low, two medium, and three high. The noise level is not that bad as you can see from the attached video. It is very important to remove the plastic bag
