Dyson cleaning products are loved by many (including us!) for their efficiency, reliable power and intelligent design. They can also cost a pretty penny. So, we recommend you don't sleep on this deal in Amazon's early Black Friday sale offerings: You can now take 34% off a Dyson Purifier Hot + Cool HP10 with a bonus filter bundle. This futuristic-looking home appliance pulls double duty, working as an oscillating tower fan, heater and an air purification system in one, cleaning the room as it cools or heats. It's another highly-rated year-round Dyson product beloved by reviewers for its long-lasting air filter, magnetic remote control and its whisper-like operation -- which one reviewer says is "perfectly quiet." Usually $609.99, it's currently chopped down to $399.99 -- matching the Amazon Prime Day price without filter. If you nab this deal today, it's like getting a deal in addition to a free HEPA filter -- a $79.99 value, according to Dyson's official website.

The HP10 uses a HEPA standard filter to trap pollutants and dust, claiming to remove 99.97% of airborne particles. Several reviewers, many of whom generally suffer during allergy season, report breathing fresher air since purchasing one. "[This] Dyson is the first purifier that we have had that has allowed us to stop taking OTC allergy medications when we are in our home," explains Dr. Mommy.

The fan has an auto-adjust feature that increases and decreases its purification progress, making for easy all-day operation. It also has a night mode that auto-dims its lights and works at its quietest setting. You can adjust the fan using a compact remote control, which is conveniently magnetic so you can tack it to the top of its tower.

This Dyson air purifier likely won't last long at this current Amazon Prime Day sale price. If you're seeking a fresher home and you've got your eye on a Dyson, grab the HP10 now because it's an in-demand deal in Amazon's pre-Black Friday offerings.
