Dyson Hot+Cool HP2 De-NOx Air Purifier — Purify, Heat and Cool in One Machine! $799.99 CAD (20% Off)

Best Buy is currently selling the Dyson Hot+Cool HP2 De-NOx air purifier in white and gold for $799.99 CAD (regular $999.99 CAD, 20% off). Free shipping on orders over $35 CAD.

The HP2 is the kind of machine that does three jobs: a heater in winter, a circulator in summer, and an air purifier year round. In a climate where the heating runs for half the year, one device covering three seasons takes up less space and costs less than buying a heater and a purifier separately.

The De-NOx part is the real upgrade, and it lives in the activated carbon stage. Dyson's testing has it capturing 50% more nitrogen dioxide (NO₂) than a standard activated carbon filter — a relevant number in urban homes, where gas stoves, fireplaces and proximity to major roads all contribute NO₂. The filter system is fully sealed: the HEPA layer captures 99.97% of particles down to 0.3 microns, the carbon layer handles gases and odours, and Dyson rates odour removal at 97% for cooking, pets and smoke.

On the practical side there are 10 fan speeds, a remote control and an indicator light for current status. Paired with the MyDyson app you can check indoor air quality and control the unit remotely, and it works with Google Home, Amazon Alexa and Apple Home for voice commands. Heating and purification are rated for whole-room coverage, with maximum setting for air projection and Auto mode for purification coverage.

It measures 24.8 x 76.4 x 24.8 cm and weighs 4.37kg, so it does not need much floor space — and with no exposed blades, it is an easier sell in a house with kids or pets.
