Review: LUFTRUM AC400 whole house air filter: Solid unit and great buy with coupon - Appears to be really well made of steel and fairly heavy. Not sure why it says 13lbs in the details? So the tiny wheels it has on are appreciated! Looks wise its a minimalist steel box that is designed to blend into the back ground which is fine by me but obviously looks are very YMMV. Controls are very simple: only has a 3 setting knob on top. At its lowest setting its basically silent but low airflow. Next up from that is only mildly louder with moderate airflow, and the last is moderately loud with high airflow. The filter appears to be well made and its claimed to have a lifespan of 6-9 months depending on the air quality. The brand name filter model is LUFTRUM AC400 with the ASIN of B0BNQ6JGFX and runs about $90 at the time of this post. For a filter of its class and claimed run time that is actually OK compared to others though still feels kinda high to me personally. There is a competing brand filter that claims (haven't tried it yet) it will fit into the LUFTRUM AC400 with similar claimed performance for about $50: PUREBURG AC400 Item #: AC400-Replacement, 19.3 x 3 x 7.9 inches. Another brand cryptically called XBWW sells a similar filter for a similar price too. Might give either one a shot when my current filter needs replacement. Replacing the filter is real easy: there is a flip up door held closed with a magnet that you open, slide in the new filter, close the lid, and you're done. Filters have a pull handle built in so they're easy to change. I put my unit into its silent setting and pretty much let it run 24/7 in the time I've owned it for a few weeks now. There have been 0 issues, just the way I like it! If you can get this model with the $100 off coupon this thing is a solid bargain over all. Without it the unit is good on its own merits but doesn't stand out much vs the competition. Other factors such as filter availability in local stores, US warranty service, etc would be factors against this unit vs a Honeywell air filter.
Review: Little to no dust - Works great hardly any dust

## Questions & Answers

**Q: Why does the ad say "made in Sweden" when Amazon says China as origin?**
A: The company that designed the air purifier is in Sweden, but the actual manufacture of the machine takes place in China.

**Q: What filter does this unit take? LUFTUM AC 400?**

**Q: How often do you change the filter?**
A: 6 months cuz we not use a lot

**Q: Any one have a customer support email address for the manufacturer?**
A: The model depicted was returned by me.  I couldn't find anybody to help me (including Amazon) locate a user's manual or customer service e-mail or phone no. for help.  I purchased an Orans model instead because of this.

### ⭐⭐⭐⭐⭐ Little to no dust
*by S***S on July 15, 2026*

Works great hardly any dust

### ⭐⭐⭐⭐⭐ Low noise, looks great.
*by K***H on March 5, 2026*

We have a very large great room with 6 gable dormers that have a 25' height and about 1900 sq. ft. We have cats and dogs and while none of us are allergic to them let's face it animal dander can make odors with multiples. This unit not only cleans the air in the great room but the hallway and other rooms as well! Amazing. Looks good. Runs quiet on low and medium. A little louder on high so I set it there at night.
