Winix HR900 is a modern approach to air purifier without sacrificing its practicality. At 16.3 x 23.6 x 9.6 in and 18.7 lb weight, it is exactly the same dimension as HR1000 so expect the same build quality. Carrying the air purifier is easy with the back handle. At the opposite side, there is an AQ indicator light that will change color to reflect on room air quality. When the bar color is Blue means air quality is good, Yellow = fair, and Red = poor. Like most Winix models, air inlet is at sides with many small vent holes at the front. Air outlet is at typical top right behind the controls.
Speaking of controls, there are 6 clickable buttons plus Smart and light sensors on top. Starting with the Power button that we are all familiar with. Right above it is the filter reset button that is only used after you replace with a new filter set. Press and hold the button for 5 seconds to complete the filter countdown timer reset. Mode button will cycle between Auto, Sleep, Low, Medium, High, or Turbo speed. PlasmaWave button will activate/ deactivate the features on press. Timer button will cycle between 1, 4, 8 hours and no timer on press. Press and hold for at least 3 seconds will enable/ disable the Air Quality light. Lastly, child lock will lock all functions when you press and hold the button for at least 3 seconds. This prevents children from meddling with the air purifier controls. To your most left, there is the Smart Sensor used to detect nearby air quality. The light sensor checks ambient light and auto adjusts the LED indicators brightness.
To recap on HR900 long list of features, you have AHAM, Ozone-safe certified, UL listed, and ENERGY STAR. 5-stage filtration with Ultimate Pet Filter U. 4 fan speed plus Auto, and Sleep mode. AQ indicator light, Child lock, and 2 years warranty.
Airflow, speed, and CADR
What’s inside count
This is called the ultimate pet air purifier for a reason. Starting with the first line of defense against pet hair and dander. You have the add-on Ultimate pet pre-filter and the standard, washable pre-filter. Both work simultaneously well with each other. Next is the AOC Advanced Granular Carbon Filter. The carbon filter will capture smoke and pet odors well and extends the HEPA life. With the True HEPA filter well-protected, no bacteria or germs will be able to fly back out. The HEPA filter efficiency is rated at 99.97% efficiency on microorganisms as small as 0.3 microns. Ending the filtration is Winix own PlasmaWave Technology. The PlasmaWave will safely break apart allergens and chemical vapors at a molecular level.Dust mites, pet dander, bacteria, and germs are no biggie for this air purifier when you have 2 pre-filter. Adding a 300 square feet and True HEPA filter, no mold, pollen, or mildew will be able to fly pass HR900. AOC carbon filter is ready to trap any pet odors plus chemicals vapor from cigarette, radon, or VOCs.
Keep it downWe don't have the official noise figure for HR900 and we are not going to test it since is similar to other Winix models. It's safe to assume the bar would be between 20 - 60 dB. In any case, Sleep mode would be the go-to setting for bed time use. Power usage is at a max 90 W (Turbo speed). It might seem high but compare with other appliances, it is not. Don't forget there is Auto mode that will manage your fan speed thus the energy consumption rate.
At what cost
^ Replacement filters/ estimated cost
Winix HR900 VS the challengers
Winix HR950Around the same price but with better purifying coverage, CADR, and anti-microbial coating. While you're at it, why not consider HR1000 that is priced slightly higher but is Wi-Fi enabled. Super cool.
Winix 5500-2Is Pet filtration really your thing? If not Winix 5500-2 would be a better bet with better airflow performance, CADR, and a cheaper price tag. Plus, it is also compatible with the ultimate pet filter.
GermGuardian AC5250PTIf you need a cheaper, slimmer air purifier with UV-C light and antimicrobial, look no further. Performance wise it is incomparable to HR900.
Coway AP-1512HH MightyJudging solely based on airflow delivery rate, Coway Mighty wins hands down. There is also the very low filter replacement cost advantage. However, purifying is more than just airflow, there is also filters to contend with.
Final thoughts on Winix HR900Is a little bit too early to judge on Winix HR900 as there are only 32 reviews on Amazon. Out of that, 97% gave it 4-5 stars that praises mostly on the 5-stage filtration strength. No surprise gave the usefulness of the True HEPA and AOC carbon filter. Other positive feedback includes durability, features, and pricing. Most reviewers are happy that their allergies reduced since the day HR900 arrived. You should expect the same outcome since most reviews are still very new. Remember this space if you want to find out about other comments users have updated since.
