works well with my second generation Airdog . one question though - how to recharge the control

Thank you for your speedy support!!

Thanks again AIRDOG 4 BEST PRODUCTS AND CUSTOMER SERVICE!! 3 AIRDOG units & love the fact the filters are washable & don't add to the garbage dumps. We were spoiled with copl clean air in the mountains of NH with filters having minimal upkeep in a home 4 times bigger. Commerce Township although looks idealic near Detroit is very polluted. Our residence is brand new,1year old. Our 3 AIRDOG get cleaned weekly full of dirt,black film from pollution around here. We're only in 1459sqft but buying largest unit from you soon. Whole time I was in NH I needed allergy meds& inhaler handful of times. In MI it's daily we both are suffering. Had our furnace and vents& flooring cleaned, the construction ppl left so much debris in the walls,vents. We love our AIRDOG PURIFICATION SYSTEMS BUT YOUR CUSTOMER SERVICE IS THE BEST!!! HIGHLY RECOMMENDED AIRDOG ONLY,we spent over 10grand for others in NH but didn't find out about AIRDOG until I looked on Amazon for ionizers air PURIFICATION with reusable filters
