To all, Do not order air purifier units from Lab Charge! I was scammed out of $120.00 by them. After many communications back and forth with them, including pictures for them I finally got a return shipping label. No response they received it so I turned it into the Better Business. I got an answer from them this morning (after a month) that they had no response from Lab Charge so the case was closed and I would have to pursue small claims court. I'm done with these crooks. Time for an attorney, bad lesson Hope no one else gets taken by these crooks. Xoxo
