I think this one has permanent filter this one as well cheaper https://www.amazon.co.uk/HoMedics-Purifier-Eliminates-Allergens-Foundation/dp/B006ZKXIXK/ref=pd_lpo_vtph_79_lp_t_2?_encoding=UTF8&psc=1&refRID=00G978VTBXPYS6PA7SGV
Totally snake oil. Waste your money folks and 'believe' it works. If It really made a difference there would be evidence from RCTs
Very tempted by this one. Allergies have been severe this summer.
Always thought these things were snake oil like the Xiaomi air purifier. I get bad hay fever, do these genuinely work?
Hi ladies and ladies, I bought this and I can confirm that it has 3 setting, quiet, intermediate and loud. The first one is very quiet and good at night. You can also turn off the led light at night. It also has 2,4,8,12 hour timer settings or you can run it on constant. It has 2 filters, I use my vacuum to clean the outer filter every 3 weeks due to the build up of trapped dust and that does the job. Very good air filtration and as a hay fever sufferer it has helped a lot.
