Aspen will positively impact the entire house by using ducts that distribute the air into and out of the room.

Incredibly Effective 3-Stage Air Filtration Process

Aspen's three custom-designed filters allow maximum airflow and filtration 24/7. Each stage of the purification process uses a different filter to remove various pollutants from your air that may differ in size. The rest of the air purifying unit is designed around the filters.

Three Unique Filters for Optimum Air Quality

  1. Allergy Filter: Removes mold, pet dander, pollen, dust mite droppings, asbestos, and more!
  2. Activated Carbon Filter: Removes VOCs (volatile organic compounds), odors, formaldehyde, chemicals, tobacco smoke, and more!
  3. Microparticle HEPA Filter: Removes 99.97% of particles down to 0.1 microns, including smoke, soot, bacteria, smog, viruses, and more!

Balancing Efficiency & Safety

Other air purifiers use technology such as UV lights, ionizers, or ozone generators that can be harmful or have adverse effects on your health. Instead, the Aspen Air Purifiers use 100% safe purification methods that are guaranteed not to produce ozone. Our unit keeps your health in mind and is safe to use day and night.

NRD takes efficiency seriously, as it contributes to your home's health and safety. Aspen Air Purifiers are built with EC fan technology and use up to 85% less electricity than your traditional AC fan. The efficiency gains are even more pronounced at lower fan speeds, which are used most frequently. Aspen will save you money on electricity while effectively cleaning your air, making this the gold standard in home air purification. It even pairs beautifully with the SaniDry Sedona, a high-efficiency basement dehumidifier. Together, the Aspen and SaniDry drastically improve indoor air quality for an overall healthier home.

The Aspen Air Purifier is simple to use and includes easy-to-change filters that slide out like dresser drawers. Its portability and easy maintenance make it a convenient option for use anywhere in your home, easily covering up to 1,500 square feet. The HEPA filter enhances air purification with intense allergen removal covering 40 square feet.
