Blueair H35i Humidifier Gen 2

Was going to give it 3 or 4 stars because it started acting weird and inconsistent operation after cleaning. Found a comment that said to fill from the top and has been working every time now. Very quiet, no white powdery or chalky dust. Fairly easy to clean with citric acid. Can be annoying to refill it every other day but beats having sinus issues.

Quality- love the ease of a ‘pour on the top’ access to add water (do not need to remove casing or tank. Part of choice was the NO Mist - evaporation technology so NO dripping of droplets in room or fine white dust - especially love the filters (can wash by hand) to eliminate air particles and and the wick technology limiting the chance of mold in tank/water/air - Quiet! Like the App control and on the canister manual controls. Set Humidity level / alerts for low water and filter cleaning or change required. Quality product - purchased for parents in nursing home- dry air hard on respiratory system and skin. Great price point / quick delivery / online order for filters (1-2 year) depending on use

UPDATE : 1 Month Later - It DIED! Dead as a doornail in a MONTH people! Will not turn on, if it does turn on, it shuts itself off, if it manages to be on and running, the water pump won’t bring water up onto the filter. I have thrown in the proverbial towel and returned it. DO NOT BUY THIS. PROS: Works brilliantly! I live in a desert and usual humidity was around 5 - 10%. I suffered from frequent nose bleeds, dry skin and dry eyes. This little unit has kept my bedroom at a very comfortable 45% humidity. I have to refill it daily, but that’s understandable! Refilling it is extremely easy with a water pitcher. I have not spilled anything. The unit is extremely quiet, and once I figured out I could adjust the brightness of the display on the app I think it is a perfect humidifier. I would absolutely plan on using the app if you purchase the device. The functionality of the top display is such that you really are better off using the app. It works seamlessly once you get the controls down. CONS: Keep in mind that when using the included QR code to “register” the device you’re only guided into signing up for the blue air promotional emails which is why I’ve knocked one star off. You’ll need to use the email associated with the app, create an account on their website, and then go to register the device under the “devices and warranty” subheading using the serial number found on the back of the unit and your date of purchase from Amazon to actually register your device for the 3 year extended warranty.

I purchased this humidifier expecting strong performance and reliable humidification, given the high price and premium branding. Unfortunately, after a full week of nonstop operation, the humidity in my room barely changed: from 38% to 40%, and only within 30 cm of the unit. The rest of the room stays completely dry, and I still wake up with a dry nose — something that never happened with my previous humidifiers. The built-in display shows 55–60%, but an external hygrometer placed right next to it consistently reads around 40%. This means the unit either measures incorrectly or produces only localized moisture that never spreads into the room. The device is placed properly on a nightstand and used continuously, but the real-world effect is negligible. Overall, this is an attractive, expensive device that simply does not work in dry winter conditions. If you need actual humidity — not just a decorative appliance — this model will disappoint.

I already have two Blueair air filters so I know that this Swedish company produces high-quality products. This humidifier was very easy to set up and I like it because it does not require using distilled water which I would need to purchase and lug in to the house. It uses tapwater and I have a device that measures air quality which I have used with it while functioning and it does not produce damaging air particles when in use. Excellent product and working well using wifi.
