Air Purifiers

The air in your home can contain pollutants that cause allergies, asthma, and an increased risk of long-term illness. A professional Air Purifier is great for cleaning your air and battling against allergies, smoke, pet dander, mold, viruses, and more.

Aspen Air Purifier

Aspen is a professional-grade air purifier that covers 1,500 square feet using 100% safe purification methods. Other air purifiers use technology that can be harmful or have adverse effects on your health, such as UV lights, ionizers, or ozone generators.

Reduces allergies, asthma, and risk of long-term illness.
Uses up to 85% less electricity than your traditional AC fan.

Unique 3-Stage Air Filtration Process

Aspen’s three custom-designed filters allow maximum airflow and filtration effectiveness. Each stage of the purification process uses a different filter to remove different pollutants from your air. The rest of the unit is designed around the filters. The filters include:

Allergy Filter: Removes mold, pet dander, pollen, dust mite droppings, asbestos, & more!
Activated Carbon Filter: Removes VOCs, odors, formaldehyde, chemicals, tobacco smoke, & more!
Microparticle HEPA Filter: Removes 99.97% of particles down to 0.1 microns, including smoke, soot, bacteria, smog, viruses, & more!

Efficiency And Safety

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

TerraFirma takes efficiency seriously, just like your 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. An efficient air purifier will save you money on electricity while effectively cleaning your air.

Our unit is safe, easy to use, and includes easy-to-change filters, making it a great option for use anywhere in your home where you want clean air. They cover up to 1,500 square feet. Our Aspen Units also include a 10-year warranty with filter subscription and a 2-year standard warranty.

Basements WATERPROOFED, HOMEOWNERS HAPPY

We take pride in our years of experience making homes dry, safe, and stable. From Ashland to Corvallis, Beaverton to Olympia, our Basement Waterproofing clients have given us great feedback.

These folks are WORTH the call and having them out! Seth, specifically, was amazing at scope, plan and presentation. He was so knowledge and really took into account all of the needs of the house structurally and visually. He was extremely professional in house and on the phone. Nothing was over sold or up sold, and every concern I had was listened to and taken into account. Every detail was in the bid neatly and nothing was out of place. If you've got a basement or crawlspace project, this is as professional as it gets. I will DEFINITELY be keeping this company in mind for future projects and for friends and family. Call. Ask for Seth. He's got you.

I had a consultation with Riley for some water damage in my basement. He was courteous (took his shoes off before coming in the house), informing and on time. It seems like this team has great communication and I will use them in the future should the need arise! My issue was a smaller drainage problem and door framing issue that needs to be addressed by a different specialty.

With a water floored basement, we contacted Terra Firma to locate the water source which they did in no time. They explained, in detail, what would be done to fix the problem and went to work. They were respectful of our furnishings covering to protect them from limited dust. They were professional and the project was completed on time. We are very satisfied with the end result, quality of workmanship, and price. We would recommend them for foundation work of any type.

Great work. I had huge foundation issues on a large waterfront project. Terra firma waterproofed my basement and lifted the house on hydolic piers to level it out. They saved my project. Seth was a fantastic project manager and Oscar and Jorge completed the job extremely well. 10/10 would recommend for any foundation issues.

We reached out to a few local companies before deciding to go with TerraFirma for our basement waterproofing. Their solution was straightforward, well explained and competitively priced.

We had a sump pump installed along with a waterproof membrane and dry track along the walls. Their team found a way to put the sump pump under the stairs so it was accessible but out of the way.

I had a few concerns that I brought to their attention after the project was finished. They went above and beyond to make sure that everything was taken care of. I appreciate that they really stood by their work.

Since the waterproofing was finished we had torrential rain (that previously would have left standing water) and our basement remained bone dry. The peace of mind has definitely been worth it.

Thanks to TerraFirma for the 3 young men Jorge, Juan and Manuel who encapsulated our basement. Always on time, working a full day and at the end of it all doing a wonderful job. Our basement has never looked or smelled better.
Thanks Michael

I reached out to Terrafirma when I needed to get an understanding as to what was causing an issue in my basement flooring. Sam was extremely professional...

We had a phenomenally difficult issue in a basement. We purchased the home in an estate sale through an attorney so no disclosure was made that the basement flooded with up to 4 feet of water in the winter. Called multiple different foundation system contractors, nobody wanted the job. Terrafirma came out estimated through job and did all the work on time and in budget. Made the renters happy also . I am impressed. Dr. Mary Fitzpatric

Our house is built in the SW hills of Portland originally in 1938, with a 2003 addition. TerraFirma waterproofing product has been a significant update to a...

We called TerraFirma with a pretty significant problem. We had just purchased a home and were a bit misled on a couple of items. The basement and crawlspace were mold infested (which we did know). What we did not know was that at times of the year, there would be some standing water in the crawlspace. We also didn't know that the drain from the sump pump was actually underwater (adjacent lake), nor did we know the pool backflushed into that same line and actually would enter the crawlspace whenever that process occured. The crawlspace was unvented and unconditioned....the perfect storm of BAD! Our goal was to first remediate the mold and then resolve the issues that allowed the mold to grow in the first place. Enter Terra Firma. Tulane and Terra Firma stood head and shoulders above every other company I spoke with. It wasn't jus that they were going to fix it- we literally walked through every step and every product-I knew what I was buying before we started. The crew was professional, on time and did exactly what they said they would do and in the time frame promised. With Terra Firma, we waterproofed and encapsulated our crawlspace, we insulated the crawlspace, we installed new sub floor drainage with new sump pumps with battery backup to lower the water table under the house (that now drains above the high water line), we installed new structural floor posts where others had rotted, we installed a bypass for the pool overflow and we installed dehumidification and we are in the process of now conditioning the space. Terra Firma led the way and did an excellent job both on the communication and on the installation (at the price originally quoted!). I would highly recommend this firm for anyone with complex and challenging crawlspace issues. Great work and fantastic team from start to finish!

Basement Waterproofing Homeowner Questions

Which vapor barrier is best for weeping walls?

The VaporLoc Elite Wall System is better for weeping walls than other commonly used vapor barriers. The VLE system has double sealed seams, waterproof material (not water-resistant), and is much thicker than vapor barriers available at retail stores.

Basement waterproofing: interior vs exterior – which is better?

Interior waterproofing generally provides the most serviceable, comprehensive, and longest lasting solution.

Will a wet basement pass inspection?

Home inspectors cannot pass or fail a home, but only call out defects and make suggestions to consult a qualified contractor.

How long does basement waterproofing last?

TerraFirma-installed waterproofing systems are expected to last decades with regular care & maintenance. We also warranty our installations, our WaterGuard and DryTrak drainage systems come with a transferrable lifetime warranty. Terms apply, view the details here. We stand by our work and the quality of the systems we install.

Should I consider a vapor barrier if I’m not planning to finish my basement?
