Could always be better, but works well.

Seems a bit flimsy for the price point, could use some more supports to help keep it stable when changing filters.
Doesn’t fit some Filtrete filters very well because they can be a little bigger, and they are one of the more reliable and know brands. Can squeeze them in but the unit can get slightly deformed. Would be nice to have some adjustment ability for slightly different sizes.
Since it’s DIY construction I added an adjustable knob for different fan speeds, and bought the pro version of the fans they recommend with higher rpm. Still very quiet at full speed.
Would be nice to have a pre-filter added or come with it to hide the furnace filter and make the main filter last a little longer.

Best pc fan air purifier on the market

I am beyond impressed with my Tempest Air purifier.

It is so quiet and so sturdy! I was a bit worried about putting it together as I am not a very tech savvy person but it was a very simple process.

I had to contact Nukit because I had a bad power source (purchased from a different vendor) and they were able to walk me through the troubleshooting process in a way that was clear, precise and easy to follow! This is a company that stands behind their products!

Highly highly recommended!

Favorite filter fan box- no duct tape!

I receive my Tempest kit, which was very well packaged. I found the instructions to be clear and easy to assemble. It looks so so much better than my DIY duct taped filter fan boxes that I've been building to keep myself and my family safer in this on-going pandemic. The design with attention to detail is important to me- such as the rubber feet on the bottom so wood floor isnt scratched. It looks great and I enjoyed putting it together. It is very quiet, the noise is really not noticeable at all. Thank-you for having this professional grade option for us!

Excellent purifier

Very quiet. Easy to put together. Zero complaints.

The Blue Air and Honeywell HEPA's are in storage now.

I love the Nukit Tempest. I live in California so we have pollen in spring, wildfire smoke in the fall and Covid year round. The Tempest is a sturdy and professional looking build that I expect to last. All that needs changing are the filters every 6 months or so, all the other parts are off the shelf if they wear out. And while that is great I am most happy with how quiet it is while on. I used to have to turn the HEPA filters off when on the phone. Tempest is a quiet white noise that just does not interfere in any way.
