AF400 Fresh-Air Series Air Purifier - QuatroPowerful, compact and portable, the Quatro AF4000 Air Purifier can handle a room that is 200 square feet (based upon an 8 foot ceiling height). Will provide optimal containment of dust, odors, and airborne particles left after polishing operations and various bench work. Many competitive dust collectors pick up much of the dust at the source, but normal polishing operations will also allow a substantial amount of dust to become airborne and settle

Powerful, compact and portable, the Quatro AF4000 Air Purifier can handle a room that is 200 square feet (based upon an 8 foot ceiling height).  Will provide optimal containment of dust, odors, and airborne particles left after polishing operations and various bench work. Many competitive dust collectors pick up much of the dust at the source, but normal polishing operations will also allow a substantial amount of dust to become airborne and settle around the shop thus why Quatro Air Purifiers are needed to sweep the air and contain even more dust.


Fresh-Air Series Air Purifiers capture airborne dust and other contaminants in an advanced three-stage filtration system, then recirculate clean air back into the room. The most important stage of this filtration system is the medical grade certified HEPA filter, rated at 99.97% at 0.3 Microns. The brushless motor is designed for long continuous use and provides quiet operation. All provide complete room air exchange approximately 15 times per hour (depending on the room size). While these air purifiers purge the air and provide a clean environment, they will also help reduce heating and air-conditioning energy/maintenance costs as well as reduce general cleaning costs. Each includes smooth casters for easy relocation from room to room as well as (3) spare dust filters. Replacement Filters for all models are available. Available in 3 sizes based on the size of your room. The AF400 uses 120V, 1.6 Amps., and its noise lever is 52-56 dBA.  This unit does not require a truck for delivery.  Made in Canada.


Features a 3-stage filtration system:

  • Stage-1 Prefilter — Captures the biggest particles, prolonging the life of subsequent filters. Inexpensive and easy to change. (see our 8541394 sold in a package of 6)
  • Stage-2 Hi-Cap Filter — Provides high-capacity particle retention. (see our 8542105 - sold in a package of 2)
  • Stage-3 HEPA Filter — Picks up 99.97% of 0.3 Micron particulate, including soot and pollen. Recirculates clean air back into the room to help minimize heating and AC costs. Replace every 3 to 5 years depending on use. (see our 8542139) 


HEPA (High-Efficiency Particulate Air) filters are designed to capture the subMicron particles that tend to pass straight through traditional Ashrae-rated filters. These particles—which can come in the form of powders, aerosols, fumes, smoke, molds, spores, bacteria and more—bypass the human respiratory system’s natural defenses, penetrating deep into the lungs where they cannot be expelled and raising long-term health concerns. For this reason, HEPA filters are critical to ensuring safety in environments where small particulate is generated. It is no coincidence that allergists, asthma specialists and air filtration specialists alike recommend HEPA filtration.

Note: When working with materials that contain silica, such as investment or tripoli, it is wise to wear a properly-rated respirator if exposure levels are high. Airborne respirable silica can be captured with a vacuum or air purifier containing a HEPA filter.

Quality, good looking shoes!
Size: 8.5, Color: Green
Absolutely perfect fit, design, and color. I'm so pleased with these sandals and as always with this brand, I am not in anyway disappointed. These shoes are so comfortable right out of the box. They clean up very nicely, and last forever. I am so glad I got these before they were sold out.

UGG Comfort Without the Premium Price
Size: 9, Color: Beige, Size: 9, Color: Beige
These sandals are super cute and incredibly comfortable. They have that classic UGG look and feel, but at a much more approachable price point. The footbed is cushioned and supportive, making them easy to wear for extended periods. The straps feel secure without rubbing, and the overall construction feels solid and well made. They’re lightweight but still have a sturdy sole with good traction. They pair effortlessly with casual outfits and have that relaxed, elevated vibe UGG is known for—just without the higher price tag. A great value for both style and comfort.

Ugg comfy shoes
Size: 7, Color: Black
So comfortable and cute as well. I wore these the first time and had to have everyone touch them to see how the sole would squish. Fit well, and are lightweight as well.
