Blue Pure 211i Max.
We love our purifier. I feel I keep a pretty clean house but since we have this I don’t see much dust at all anymore. We keep it under air return in master bedroom area. And I don’t seem to get stuffy nose at all either. We bought due to my spouse clearing his throat a lot. Seems to have improved too.

Clean air, even with dogs and cooking
I love this air filter. The air seems cleaner, strong smells dissipate faster, and it just feels healthier inside my house. The filter was fairly easy to put on the machine although a tight fit, and the cover is attractive and stretchy.

Water Tank
The water tank is dishwasher-safe. You can also hand-wash it using mild detergent and warm water. Never use bleach, harsh chemicals, or chemical solvents.

Wick Filter
Clean the wick filter every 2–4 weeks. Soak the wick in a descaling solution using 1 descaling packet per tank of water for 2 hours, then rinse thoroughly with clean water.

Be sure to replace the wick filter every 6 months for optimal performance.

Bi-Weekly Cleaning Guide + -

To keep your DreamWell Humidifier performing at its best, Blueair recommends cleaning it at least once a week, or twice a week with regular use. Always disconnect the device from power before cleaning.

Water Tank

Clean the water tank with a mild detergent, or place it in the dishwasher.
Dry the water tank thoroughly before reassembling the humidifier.

Wick Filter

Soak the wick filter in a citric acid solution (20 g of citric acid per 1 L of water) for 1 hour. If needed, you can soak it for up to 2 hours.
Rinse the wick thoroughly under running tap water before reinstalling it.
If you have the DreamWell mesh fabric replacement wick, it can be machine washed on a gentle cycle.

Wipe the exterior with a soft, dry, or slightly damp cloth to remove dust.
Do not submerge the upper body in water.

Invisible Mist Monthly Descaling Guide + -

Follow the steps below to safely and effectively descale your humidifier using citric acid descaling powder. Before you start be sure to unplug the device, remove the visible scale from the inner tank surfaces by rinsing with fresh water and wiping with a clean towel.
