Frequently asked questions
How we talk about particles, why HEPA is the hero path, and what this site will never do.
Why is smoke / HEPA the primary path?
Wildfire smoke now reaches cities from the Pacific to the Atlantic. A portable true-HEPA purifier with a published CADR is the appliance that actually addresses airborne particles. Humidity gear is seasonal and secondary. We are skeptical of miracle indoor-air claims; we would rather size a boring HEPA box than promise a health outcome.
Do you claim these products treat asthma, allergies, or other conditions?
No. This is not medical advice. We describe particle capture and CADR. We do not claim prevention, treatment, or cure of any medical condition. Talk to a clinician for health questions.
What does CADR mean here?
Clean Air Delivery Rate is a lab measure of how quickly a unit delivers filtered air for dust, pollen, and smoke-sized particles. We use it as a sizing hint, not a health outcome. A “covers 1,000 ft²” banner is often one slow air change per hour — not a smoke-day bedroom.
Why Amazon.ca and Prime language?
Smoke weeks and January dry spells are time-sensitive. Listings that ship from Amazon and qualify for Prime usually arrive faster and are easier to return than long-haul marketplace stock or Amazon Global Store. When we cannot confirm fulfilment, we mark VERIFY and we demote weak merchant-fulfilled hero CTAs.
Are the prices exact? Do you invent stock?
No. Every dollar figure is a CAD VERIFY placeholder from a snapshot, not a live price or an in-stock guarantee. Click through to Amazon.ca for the live price, seller, and fulfilment line. We will not invent live inventory as fact.
Amazon Associates disclosure — how do the links work?
Canada Air Comfort Lab is a participant in the Amazon Associates Programme. Product cards and many in-copy links go to Amazon.ca in the form https://www.amazon.ca/dp/{ASIN}?tag=aircomfortlab-20 with rel="nofollow sponsored". If you buy through those links, we may earn a commission. That commission does not change the price you pay. We do not publish commission rates. The tag aircomfortlab-20 is wired consistently and is PLACEHOLDER VERIFY until the Associates account is created.
Do you generate HVAC leads?
No. There are no quote forms, phone harvests, or contractor hand-offs. The only commercial path is Amazon.ca Associates links tagged aircomfortlab-20.
Ontario in the GitHub name — is this an Ontario-only site?
No. The public brand is Canada Air Comfort Lab. Guidance is written for Canadian homes nationwide. Ontario winters and basements show up as examples because they are familiar, not because the lab stops at the provincial border.
Should I run a humidifier and a HEPA unit together?
They do different jobs. HEPA reduces particles that pass through the filter. A humidifier adds moisture. On a smoke day, close windows and run HEPA; do not treat humidity as filtration.
Will a basement dehumidifier get rid of mould?
No. It can lower airborne moisture if the space is closed and the unit is sized and drained. It does not remediate existing growth, fix a leaking foundation, or replace an inspection. We will not oversell that job.
