Clean Air Kits

Not exaggerating when we say an Exhalaron next to a college kid’s bed (and their roommate’s for even more chances) will substantially help avoid whatever illness the other roommate brings to the dorm. There is no downside except cost, so we discounted it for you as much as we could to help with back to school shopping.

Important reminder from our neighbors to the north.

Though our air purifiers can help keep your indoor air safe during wildfire season, filters should be changed after a major smoke event as their electrostatic properties can be compromised.

Amongst the dismantling of American science, let’s celebrate a community-grown milestone.

Our Merv13 PC-fan Luggable XL Ultra has been certified by EnergyStar as 2.4x more CADR/Watt efficient than any HEPA in their database!

This is a real testament to the social-media hive mind that formed around the CR Box to deliver clean air in classrooms.

We collectively discovered and optimized a much more efficient, quieter and speedy operating point for cleaning virii, pollutants and allergens from air, with help of PC gaming fans and common high-grade MERV13 furnace filters!

CleanAirKits is proud to receive this validation of our designs and continue supporting our customers and the open-source community of CR Box tinkerers!

Amazing Mobius 120P Upgrades!

The 2400 rpm CoolerMaster Mobius 120P is the quietest, most energy efficient fan we’ve tested. It punches higher pressure and cfm than the 140mm Arctic P14 so selected kits reach higher CADR with less fans.

First we put the Mobius 120P in a Luggable XL to create the XL Ultra with better specs than the XXL in a more compact form with easy-to-source 20x25” Filtrete.

Now 4 Mobius star in a noise-balanced mix with 6 SickleFlow in the refreshed Cherry Tower of Power.

If you’re needing a bit more zoom for your existing EndTable or Luggable XL enclosure, order our XL to XL Ultra 7-Mobius upgrade kit!

Yesterday, RFK took an ignorant dump on , and the China tariff war also threatens all the innovation by and us in the PC-fan clean air community. On Nov. 8, we took an emergency loan from 401k to bring in several months supply. After that, will be lights out!

We like the aesthetic of our purifiers, but our customer Natalie took it to the next level by adding wallpaper decals to her Luggable. If you’ve done this to yours or are now inspired to, show us your results!

P.S. Luggables and Brisk Boxes (which can be turned into a robot or other creation by adding googly eyes and some paper towel roll arms) are 10% off through Feb. 7 with discount code ANTITARIFF (because you know why 🥴)

You need to change your filters as often as every 2-4 weeks if you’re in an intense smoke area. Add a carbon sheet to one side of your Luggable, Tower of Power, Aerating End Table or Brisk Box to tackle the gasses. After you get the all clear, change your filters one more time for a fresh start.

We are deeply sorry that so many of our friends and customers are dealing with the LA fires and aftermath. We are still catching up from the holidays, but if you place an order to help mitigate the effects of these fires, please tell us (DM is fine) so we can try to move you up in the queue and get yours delivered sooner.

10% off the beloved Exhalaron (and its larger sibling, the Triple Exhalaron) through Dec. 25! Use discount code: WinterPrep

We’re hearing more and more of our customers’ success stories where one family member brings an illness home but doesn’t pass it along to anyone else (now that they have multiple PC fan quiet-yet-powerful purifiers from us).

If you have zero purifiers, start with one for the sick person’s room, and build out from there as you’re able. Many of you know we don’t have sales often, so we’re trying to help you get ready for the next surge of cases.

Tell us your winter goals about avoiding illness, and we’ll PM you the code.

Did you know our Exhalarons are inspired by Cross-Table Exhalation Study? This is also why we encourage you to place them in this particular way.

Why use Exhalaron Tri or the original double-barrel Exhalaron as a table centerpiece instead of trying to clean an entire room with them? Experiments conducted by University of Colorado Boulder, Donghua University, and Marriott Hotels demonstrated that a 98 Clean Air Delivery Rate cubic feet per minute purifier on a 4-person table will directly capture about 3/4 of exhalations before they cross the table, reducing virus deposited on occupants up to 95%.

We created the Exhalaron series to silently tackle this scenario, and now several parents have told us they're sending Exhalarons to school this month with their children to place on desks and in the middle of group tables. We also know office workers who use multiple Exhalarons to create a wall around their cubicles.
