Philips Automotive GoPure 3211 Car Air Purifier

Suckers air though filter hence absolves dust. Filter is small so will clog in say a month or so. Expensive filter replacement would be required at Least 2 to 3 times a year. Even then the volume of air handled will take a lot of time to take effect. Making this filter a placebo. Pros. Cheap, acceptable sound level, noise fitting on hand-rest. Cons. No pre filter , expensive filter replacement, low suction,.

It's very basic. It works but the sound of the fan can be irritating. It would also have been nice to have a on off switch.

Just a plastic box with a fan & a filter. No switch, no indicator. So don't know if it's doing anything or not.

not so useful

It has filter. It has a fan. It filters. Does it improve the atmosphere inside the car? May be. I really couldn't make out any difference. I use it as a scent diffuser now. The fan makes a slight whining noise which you may find annoying after a while. I have placed it far away near the third row of seats in my Endeavour. To sum it up, I really don't know if it actually makes a difference.
