Filters And PerformanceComplimenting the cool, fresh air is ULTTY Bladeless Fan Air Purifier R21 Medical Coating 3-Stage filtration. A conventional and dependable filtration setup that many of us would be familiar with. To start off, you have an iron pre-filter that captures large visible particles like dust, pet hair, and lint. With most PM10 particles trapped, the protected H13 HEPA filter will capture 99.97% of PM2.5 particles like mold, pollen, pet dander, bacteria, and viruses. To prevent captured microorganisms from thriving, a silver-ion medial coating is applied on the filter to prevent the germs from regrowth. The only thing missing in the filtration is an activated carbon filter that would help with smoke particles.
Noise And Energy UsageWhen operating at the lowest speed, ULTTY R21 Bladeless Fan air purifier produces low noise under 32 dB. When running at a max speed, there is a clear whistling noise coming from the fan that is not everyone's cup of tea. Depends on your own preference, some might regard it as pink/ white noise while some absolutely can't stand the whirling sound. If you are planning to use it during bedtime, just keep it at the lowest speed. For power usage, ULTTY R21 100-240V ~ 50/60Hz has standard power usage that will not create a burden on your utility bill. You can run it comfortably day in day out in the background.

ULTTY R21 Bladeless Fan VS The Challengers
Blue Pure Fan PurifyingA premium minimalist fan purifier from a reputable Swedish brand. Uses a single particle filter instead of multiple filtrations.
Dyson Pure Cool TP01The most fierce competitor from the brand that it is well-known for. Better airflow performance but at the cost of a bulkier body.
Lasko 42 Wind Curve Tower Fan Ionizer T42950A classic tower fan air purifier with a little twist. It comes with an ionizer that can remove pollutants in the air without the need for a filter.
Final Thoughts On ULTTY R21 Bladeless FanBeing a less known brand, ULTTY R21 Bladeless Fan still receives plenty of compliments from its buyers. The 90% 4-5 star ratings received focus on few things: the lightweight design that is very easy to use, silent operation that produces minimal noise, and excellent temperature control. They feel their indoor quality has gradually improved with less sneezing and coughing symptoms. The low price point is also another common praise where buyers will use Dyson as a benchmark. Only 5% of the users did not like what they received and most likely opt for a return. The complaints mainly focus on incomplete or damaged packaging, defective remote control, or limited airflow output which is contractive to the good feedbacks. Again the negatives are just too few to deter the positive reviews.
