I can understand that choosing the best air purifier can be a little difficult considering there are so many out there. But if you’ve settled on the fact that you are in the market for the best personal air purifier, then you should definitely have the Airdog FitAir Portable Air Purifier on your watchlist. Why We Like It - Airdog FitAir Portable Air Purifier The Airdog FitAir Portable Air Purifier is a powerful little unit that can capture harmful particles instead of just shooing them away. The True HEPA Filter will capture them so you’re always breathing clean air, and the 25 square feet of coverage is a really impressive range too! Power/Speed The Airdog Air Purifier possesses a high volume of air flow because of the 290 ports of high porous inlets which allows for a maximum air flow of 130L/min. You can also check out the AirTamer A310 for another example of a powerful device. Battery life on the Airdog, however, is only six hours, which is much shorter than other personal air quality filters. Efficiency The Airdog has a very impressive working range of 25 square feet around your personal space. That’s about 10 square feet more than most other personal clean air purifiers. You can also check out the Dyson Cool Me for a fresh air purifier with similar range. It’s power consumption is only three watts too, so it won’t cost you much to charge it when the battery runs dry. Versatility The Aidog uses a True HEPA Filter Life that can catch all manner of harmful contaminants like pollen, odor, viruses, and smoke. Speaking of smoke, check out the Smoke Buddy Air Filter if you want to live healthier with a dedicated smoke-removing purifier. But because the Airdog uses a filter instead of ions it can capture the particles instead of just shooing them away! Durability Believe it or not, the Airdog actually has three fan speeds depending on your purification needs. The downside is that the lowest possible sound it can make is around 20dB, which is about the sound of rustling leaves. That’s not bad, but at higher levels the sound is going to be quite noticeable. Especially considering you're going to have it near you the whole time. Value The Airdog comes with the FitAir app which allows you access information about the air quality around you, check the battery life, and check the HEPA Filter life. Or you can set-up notifications for these things. It’s not available right now, but traditionally it’s been priced at less than $100.00. Honestly, it’s a decent price for one of the best ultralight air solution anywhere. Airdog FitAir Portable Air Purifier Wrap Up The Airdog Air Purifier is an impressive showing. While it does take its cues from bigger, filtered air purifiers at the cost of battery life and noise, it’s cleaning power is virtually unmatched. The fact that it can actually capture instead of just redirecting is a huge advantage, or at least something that sets them apart, for Airdog.
