Making Healthy Choices

Many of us don’t think much about the quality of the air inside our homes until we begin experiencing symptoms of allergies, lung irritation, asthma and the like. If you or someone who lives with you has developed such symptoms and finds them to be worse when at home, it’s time to get serious about your indoor air quality. We’ve seen countless cases of drastically reduced and even disappearing symptoms when quality air filtration is added.

Wide Range of Products & Systems

Washington Natural Gas offers everything from air scrubbers to electronic air cleaners to filter out dust, pollen, pet dander, spores and other airborne impurities. No matter what your air quality and filtering needs may be, we have a system and products to help you breathe easier and be healthier.


Ultra-Pure Specialist

We recommend, sell and install Ultra-Pure air quality products that utilize a 9-fold air purification system to keep your indoor air clean and safe. With automatic sensors, negative ion generation, HEPA filters and more, very little gets past an Ultra-Pure system.
