Your Clean Air Solution

Experience the ultimate in effective, efficient, safe, easy air purification with Aspen.

Our Aspen has been a game changer. We actually returned it because we didn't think it was providing us much benefit and we were moving soon. And then we had the worst two nights' sleep of our lives. We purchased it right back and will never be without it again. The product is really a life savior.

We have 3 other brand air purifiers running and one commercial grade ( I won't mention name ) that was described to be the largest carbon filter on the market still not clean the air as good as the Aspen - I am thinking of second one just for the basement and throwing all others away.

Aspen Air Purifier completely changed the air quality in our house. We have used numerous air purifying devices for years battling poor air quality in our home. After using Aspen Air Purifier for about a month I can truly say that the air quality in our house has changed dramatically. We have fresh clean air to breathe… Thank you so much

I didn't have to take excedrin every single night just to be in my house. My son didn't have to use nasal spray any more every night. A long story short, this changed our lives. Now that the mold is gone, it runs still all day every day.

Last year the smoke filtered into our house even with all the doors and windows closed... This air purifier completely gets rid of the smoke. Completely! Expensive but exceptional and worth the money.

I have had severe pollen allergies in the Spring for over ten years. I have tried almost everything receiving little to no relief. We are currently in peak season for pollen and the Aspen has far exceeded my expectations! I CAN FINALLY BREATHE COMFORTABLY and RELAX in my home!

This is a game changer to the air filtration industry. We have one in office and one at home. People both employees and visitors to my home have asked what I have done to make house/office feel and smell so much better. I just point to the ASPEN.

I was skeptical about buying an air purifier but after having our newborn son I decided to make the investment. Normally my allergies are pretty bad this time of year but this year I haven't even noticed them. We've tried the mini ones from Amazon in the past but they are noisy and don't seem to help reduce my allergies. So far I'm impressed!

Clears Heavy Smoke

Aspen easily removes harmful smoke particulates from combustion sources.

Why Aspen?

• Best filtration system

• Completely safe

• Ultra efficient

• Easy to use

3 Stage Air Filtration

A filtration system with certified HEPA filters and granular activated carbon removes more than 99.97% of particulates at 0.1 microns including dust, pollen, pet dander, mold spores, smoke, odors, smog, bacteria, viruses, radioactive fallout, and VOCs from your air. Aspen removes the fine PM2.5 and smaller particles that can enter deep into our lungs and cause life-threatening illness.

Safe Technologies

Some air purifiers use technologies that can actually be harmful to your health or have other adverse effects, such as UV lights, ionizers, or ozone generators.  Our units are guaranteed not to produce ozone, and we use 100% safe purification methods

Ultra Efficient

Aspen uses EC fan technology, which can use up to 85% less electricity than a traditional AC fan at a given air flow volume. The efficiency gains are even more pronounced at lower fan speeds which are used most frequently.

An efficient air purifier will save you money on electricity while effectively cleaning your air.

Easy to Use

Designed with simple intuitive controls, so you can spend less time messing with complicated menus, schedules, and apps and more time enjoying clean air. No more complexity or connectivity issues.

Made in America

Assembled in America

Our units are proudly assembled in the USA in Seymour, CT using the highest quality fans from Germany.

Allergy Filter

With a MERV 14 rating, it's more than just a pre-filter. It removes allergy and asthma causing particles including dust, pollen, pet dander, mold spores, dust mite droppings, asbestos, fiberglass insulation, sneeze droplets, and other PM10 and PM2.5 pollutants so you can breathe truly clean air.

Independently tested to ASHRAE 52.2 standards to meet MERV 14 performance.

Activated Carbon Filter

Custom designed for Aspen, this filter contains 3.3lbs of activated carbon that captures and removes odors, formaldehyde, tobacco smoke, and VOCs from cleaning products, paint, and other chemicals. These extremely tiny particles get trapped in the microscopic pores inside the activated carbon granules.

Microparticle HEPA Filter

This hospital grade filter removes fine and ultrafine particulates including smoke, smog, bacteria, viruses, radioactive fallout, and other pollutants that are small enough to enter deep into human lungs and cause life-threatening diseases over time such as ischemic heart disease, stroke, COPD, and lung cancer.

Independently tested to IEST-RP-CC001.6 standards to remove 99.99% of particles at 1.0 micron, 99.97% of particles at 0.1 microns, and 99.98% of particles at 0.002 microns.

How big of a space does it cover?

The short answer is 1,500 square feet.  The long answer is it depends on several factors such as, how many air changes per hour you want.  For example, given Aspen's pollen CADR (Clean Air Delivery Rate) of 442 CFM and smoke CADR of 373 CFM we can calculate the room size (assuming 8 foot ceilings) for different air changes per hour.  An air change is when the entire air volume of the room goes through the unit.

Air changes per hour vs. room size (pollen CADR)

1 - 3320 sq.ft.

2 - 1660 sq.ft.

3 - 1105 sq.ft.

4 - 830 sq.ft.

What room should I put it in?

It's best to put Aspen where you spend most of your time or where there are higher levels of pollution.  Most people put Aspen in the living room, kitchen, or bedroom.  If you only have one Aspen and a two story house, it's best to put it on the lower level because the natural airflow through a house is from bottom to top due to the stack effect.  This will allow the air in both the upstairs and downstairs rooms to be cleaned.

How often should I change the filters?

Every 12 months.  A light on the control will turn on when it's time to change the filters.  If you have excessive dust, from woodworking for example, you may need to change the Allergy Filter more often.

Is Aspen a solution to radon gas?

Aspen by itself is not a solution to radon gas. If a homeowner has radon, they still need a radon mitigation system. However, radon decay products (polonium, bismuth, and lead) are metals that can easily attach to dust and other particles in the air. Aspen will capture those dust particulates and any radioactive debris attached to it. In this way, Aspen can make a great addition to a radon mitigation system.

Can HEPA Filtration Remove Radon Decay Products?
Does Aspen remove CO2?

No!  Aspen does not remove CO2 from the air. No air purifier does.

Does Aspen have a warranty?

Yes, Aspen comes with a standard 2 year warranty. This can be upgraded automatically to a 10 year warranty if you create and maintain a filter subscription within 2 years of purchase. More details can be found here.
