How does LUFT compare to HEPA?

HEPA only traps pollutants:

LUFT purifies them with patented photocatalytic tech:

LUFT destroys pollutants that are too small for HEPA

LUFT is the ONLY filter that destroys formaldehyde

3rd Parties Verified - We've test it inside and out

LUFT has NO replacement parts - and NO byproducts

How did we make LUFT Duo even better?

Twice the power, half the noise:

We listened to your feedback, and the third generation of Luft has an expanded range of 240 square feet. You’ll only need one Luft Duo for your entire house.

Same great mesh metal filter - now with super hydrophilic and self cleaning:

And one more thing:

While sleeping at night, turn on the night mode setting. Night mode is with darker light and quieter running sound. Let you sleep well until morning.

How did we get it so quiet?

The secret the is in the curved top.

The new generation of LUFT Duo uses patented 3D photocatalyst design. The patented structure increases efficiency by 62% from the previous model.

It's not magic, it's LUFT.

Here are some awesome extras for early backers:

With your LUFT cube you get a FREE cupholder and vent cap

Use the vent cap to get the most fresh air - up to 15x that of room purifiers. The cupholder can be used to use LUFT in your car without worrying about it falling or getting damaged.

From our backers

I purchased 2 Luft Cube here a while back. I love it. It has helped tremendously with how my family and I breathe when we sleep at night and during the day, especially since we’re inside the house almost all the time. I have it on almost all day long, switching between low and high throughout the day but it’s on all the time. Thank you for creating this amazing product.

I received my Luft Cube a couple weeks ago, and putting it next to the cat litter box has made me a believer. I used to be able to smell it every time I walked into the large living area where the litter box was housed, but no longer. It has been running 24/7 since I received it and no problems so far. I personally find the fan very quiet, and the lighting unobtrusive. I am very happy with my backing, thank you!

Thank you Luft cube team! I have used the cube for around 2 weeks already. The very next day, my wife stop her every morning uncontrollable sneezing due to sinus condition. She has been sneezing for years and now it has stopped for the past 2 weeks since starting using the Luft cube. Thank you very much from.
–Royston Teo | Singapore

Love these things! Use 1 at home in the bedroom, use 1 in the office at my desk and I gave the other as a gift. The Luft Cube has exceeded all expectations. Quiet, powerful, efficient, portable and high quality. Looking forward to ordering more for more areas and more gifts. Thank you.
–Michael Johnson | United States

Had a pair of these for about 2-3 weeks now, and must say I’m pretty happy with them. Wis-per quiet even on high. And they have helped clean the air in my personal space quite well!
