T800

Cylinder shaped air purifiers are generally well regarded for small rooms due to their 360 degree airflow, compact footprint, and efficient particulate removal. I myself use Mi Air Purifier 4 for my small bedroom. The Winix T500 you have mentioned have 4 stage filtration system (pre-filter, carbon, true HEPA, and PlasmaWave), quiet operation, and smart features like auto and sleep modes. It removes 99.99% of particles as small as 0.1 microns, and includes WiFi/app control for convenience. It is a good option.

Both of my Winix air purifiers started smelling like smoke, they are different models, cleaned weekly and filters changed regularly, I don’t recommend them.

I have the Winix. No issues to date. I don’t use the plasma wave feature.

We mainly use the winnix ones. They are fantastic.

Definitely recommend Winix. Australian and comes out top of various tests. (If you haven’t been warned- don’t buy Dyson) Super sensitive to more than just particulates and has a ‘pet filter’ that is changed monthly that goes around the main filter and prevents it getting clogged with dust. Helps to prolong its life if you have pets

I say about 1/3rd of my Winix's have a bit of a smell that dissipates quite quickly.

AVOID DYSON AT ALL COSTS!!! They look cool but are RIDICULOUSLY overpriced for what you get. Spent $500+ on one and my cheaper Winix outperforms it by a mile. Total marketing scam.
