The AirDoctor AD 3500 did not impress us with its appearing . With its orthogonal figure and white , glossy aerofoil , we think it looked more like a mini fridge than an atmosphere purifier . However , this extremist - basic design has some vantage . If you do not require your aviation purifier to draw much aid , the AirDoctor AD 3500 will be right up your street . Its indicator lights can be switched off when needed , and its ascendence panel is very visceral to use , too .
We also like its lightsome and portable bod . The AirDoctor ’s AD3500 weigh 18 pounds ( 8.16 kg ) , which is surprisingly little for an air purifier that can extend up to 1,260 substantial foot ( 117 straight meters ) . When we first picked it up ( which can be easy done thanks to two deep ridges conveniently located on the face ) , we even questioned whether we may have receive a incorrect unit . But no , the AD3500 really is that sparkle . It is a great alternative if you lack posture or involve to move the unit around frequently .

The impertinent - enabled option , the AirDoctor AD3500i , costs $ 50 more and declare oneself features such as remote control , melodic line quality readings and filter alteration alerts .
We like this approach . Some citizenry enjoy high - technical school trumpery , while others do not need or care about them , and it is rare to see a make that supply to both of these radical simultaneously . Nevertheless , we still recall both model are on the expensive side .
The AirDoctor AD3500 is equip with three filters : a pre - filter to captivate large particles like dust and pet hair , a carbon copy / VOC filter that bump off odors and fickle constitutional compounds ( VOCs ) , and an UltraHEPA filter designed to trap 99.99 % of ultra - o.k. particles down to 0.003 microns in diam .

There is one caution , though : The airflow in the AD3500 is very powerful . When this atmosphere purifier kicks into high gear , it almost resembles a tugboat fan .

After half an 60 minutes , these values rose even further — to 91.5 % and 100 % , respectively . We obtained similar results when we repeated the run in a unlike room .
We catch even better results during our smoke tests . First , we burned 10 matches , then we ran the AD3500 for 15 and 30 minutes on its automobile background . After 15 arcminute , our AirDoctor had vacuum up a staggering 98.9 % of 0.3 - micron particles , 99.95 % of corpuscle assess 2.5 microns , and all the pollutant larger than 10 microns . 15 arcminute later , the aviation quality was comparable to the service line measurements . When we did the match tryout on the highest setting , most all particles were go after 15 mo .
Next , we burned five incense stick and take over the procedure . The AirDoctor AD3500 trap nigh all corpuscle after 15 second , and just like in the match test , the air quality after 30 minutes repay to the service line layer .
