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.

Advantages

  • Removes more than 99.97% of particles down to 0.1 microns.
  • Reduces allergies, asthma, and risk of long-term illness.
  • Uses up to 85% less electricity than your traditional AC fan.
  • 3-stage air filtration process for maximum air purification.
  • 10-year warranty with filter subscription and a 2-year standard warranty.

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.

We had a great experience with TerraFirma. The crew that waterproofed our basement were Aris, Manuel, and Cristian, and they were super pro and cleaned up everyday after work. This crew was just great, they were friendly and worked hard every day. Give these guys a raise!
Jorge V. Juan B. And Manuel J. We’re a great crew waterproofing my basement. Thanks guys. It was a pleasure working with you.
James and his crew were efficient, kind, and exceeded my expectations. My foundation was needed piers both outside and in the basement, yet they were quick and cleaned up. I even noticed a change in my home’s interior when it was fixed! Cracks closed up. They took care of the whole process, including permits and inspections. And, James communicated, including walking me through, clearly listening to my responses.

I recommend TerraFirma, especially James who was the foreman on my job, especially to those who want to be respected, want to understand what is happening, and want good communication throughout the job.
From beginning to end, we experienced professional attitude and work ethic.
All the employees we interacted with were pleasant. They finished the job in two days even though they ran into an issue. All work was completed and cleaned up very nicely. We are pleased with the finished product. It is reassuring to know we will NEVER have water intrusion in our basement ever again!

Sam was able to provide an excellent inspection and honest report of my crawlspace waterproofing needs. Didn’t feel rushed or pressured. Was able to educate me to better understand the issues and risks. Thank you so much Sam
Bailey came out and gave us a quote on some crawlspace waterproofing. He was very knowledgeable, professional, and a pleasure to work with. He was insightful and gave several good recommendations, ultimately putting together a great quote for our work with a couple of different options. I would highly recommend giving these guys a call for your next project.
We discovered water in our basement this past April and first called the competitor who had installed a waterproofing system back in 2015 for the previous owners. Unfortunately, their visit wasn’t very helpful -- they didn’t offer a clear solution or give us much confidence that they even wanted to do any work on our 115-year-old house. That’s when we reached out to TerraFirma for a second opinion, and it was the best decision we could have made.

From the very beginning, Jaden, our System Design Specialist, was outstanding. He was thorough, thoughtful, and really listened to our concerns. He walked us through options, answered all our questions, and came up with a solution that felt right for our home. Scheduling with Sammy was easy and helpful - she worked around our vacation schedule, and we always knew what was happening and when.

When it came time for the work, Rocky and his team did an excellent job installing our new egress window, while Jorge, Juan, and Scott rebuilt our failed irrigation system from the under-ground up. Both teams were incredibly professional: always on time, tidy, communicative, and respectful of our neighbors (no small feat on our tight street with all the equipment and materials). Rocky went above & beyond with the window - making adjustments to the position and reinforcing our load bearing areas, and Jorge offered alternative and better solutions for our new sump-pump location that would ensure the functionality of our new system for decades to come.

Every step of the process with TerraFirma exceeded our expectations. We honestly wish we had found them sooner for all our home projects. They turned what started as a stressful basement issue turned into a smooth and positive experience. Highly recommend! Thank you all for your help - we're so happy with how everything turned out!
So we had Jorge, Juan, and Brad do an encapsulation of our basement crawl space and they did an amazing job. The area they had to literally crawl around in to complete the work was incredibly tight yet they completed their work without complaint and with style. It looks great! The work these guys had to do was tough, give these men a raise! They earned it!

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?
