Munchkin True HEPA Air Filter Replacement for Air Purifier, 1 pack

This nifty little product is an ideal size and perfect to be used either at home or whilst out and about.It creates a bubble of clean air anywhere I go and with 4 air speeds will automatically adjust to the right filtration speed.I can not recommend this product enough.Highly recommended!

Decent battery life. We have used it on flights successfully.

This little Munchkin is an effective little unit and great value for money. Its design is almost identical in shape and size as a regular can of lager. The replaceable filters are cheap and easy sourced on Amazon. It lasts for hours on its own battery but it has the benefit of pass-through charging, where you can be using it while charging it. Very useful if most people will be using this in their vehicles.The true HEPA filter is of a standard that it will definitely improve the quality of the air in your vicinity (due to its small size its effectiveness is limited to volumes such as the cabins of cars or tiny rooms) . It has manual speeds to cycle through, one being "turbo", which does pack a punch for its size but where the battery will run down within the hour (if not plugged in to a power source).It also has an air quality monitor built in. I am unsure the mechanism by which it measures the quality of the air, suspecting it is measuring particulates using light. However it measures air quality it seems to be effectively responding - showing green & blue LED band around the unit when air is clear or moderate and red when polluted. Blow a puff of cigarette smoke towards it or burn the toast and it will quickly turn red.Overall a great little portable air filter. Only reason it didn't get 5 stars is that it will likely break if dropped onto a hard floor. Not really a problem if your careful but something to consider if you are planning on moving it around a lot. I bought another as a gift and the recipient was also impressed with it.

This is a very small device, which has a little fan and a hepa filter in it. The control over the speed or any function on this device is extremely hectic, you try to follow the instructions, but the fan doesn't do what you want or when you want it. It looks like it has its own life, you can play endlessly with it. If you are board and has nothing to do with your life, buy this product definitely.

I've had this little air purifier for a while now I like that I can recharge it via USB when I've got my laptop on, then being free to move and place it without the need to a nearby socket.I found it really handy in the summer when the temperatures were high. I had it close to me at night when I was watching TV, I found the fan isn't really really loud and distracting, yet it was quite cooling around my face, making it easier to breathe.It won't purify the air in a bi room, but for close, personal use I would definitely recommend.

I really liked the size and quietness of this product but, sadly, I didn't find it suitable for my needs. I got a little tired of having to charge, which made it unavailable for me to use.

I take this on the tube & train. On the basis it can't hurt. Likely more effective in a car setting due to size, but the breeze emitted is nice & it is quiet to run on it's most powerful setting.

I got this to take to uni with me, so I needed something small enough to carry on top of all the extra books I'm lugging around. It's quite discrete - when it bumps up to full throttle it is quite noisy, but also prompts me to open a window if I can, so also works as a useful indicator of air quality for those around me!It's really lightweight, about the same size as an average water bottle (500ml-ish) and the filters are easy to change. Charging is straightforward and it has yet to struggle to make it through a day of use, so I'm very pleased. In terms of covid, please remember: it is v. small so effectiveness drops the more crowded an area you're in. Best to combine with masks where possible!
