Let customers speak for us
Bought 2. Easy to install. Nice to
buy from a local BC company.
Excellent quality, well built. Good delivery. All good.
We moved to a house with the cheapest builders-grade cold air return grates/grilles/registers. The layout of the house put them in very visible locations. While looking for an upgrade, I discovered the insanely high prices for something better looking. Then I put the words “diffuser” and “Canada” in my search. Linear Air Diffusers had exactly what I wanted! Well made, high quality, adjustable grilles. An exceptional value, I immediately ordered three. (Yes they work as intakes too). Perfect fit for the 10x16 openings. Installed with Velcro for a screwless custom look. Adjustable vanes helped with furnace noise in one of the bedrooms. Couldn’t be happier.
We have used these on several jobs and are extremely pleased with the way they Proform and the look. Last job we installed these in a large church to project the air to better stir the air in the room and the worked very well as planned.
Good as promised, good as expected.
I’m a returning customer for a few reasons... Sturdy construction, easy installation, the vents show up as ordered, and good communication. Highly recommend!
Quick shipping, product as advertised, would recommend.
I knew about the fair price and the product being in stock and off the shelf ready for shipment. I did not know or even expect -----

Awesome, exactly as advertised.
I recently purchased linear air diffusers and couldn’t be more satisfied with the entire experience. The quality of the product is absolutely top-notch—sleek, durable, and designed to perfection. They added a modern and clean look to my space while performing exceptionally well.
There was a slight mix-up with my order, but I was incredibly impressed with how efficiently and professionally it was handled. The issue was resolved quickly and at no extra cost, showing their dedication to customer satisfaction.
Shipping was also impressively fast, and the diffusers arrived well-packaged and in perfect condition. I highly recommend these diffusers and this company for their excellent products and outstanding service!
Smooth communication from beginning till end. Highly recommend, very professional.
