Incredibly Effective 3-Stage Air Filtration Process

Three Unique Filters for Optimum Air Quality

Allergy Filter

Removes mold, pet dander, pollen, dust mite droppings, asbestos and more!

Activated Carbon Filter

Microparticle HEPA Filter

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.
