They did the same to my elderly father with dementia. Called him offered a gift  claimed the machine would help his dementia. The salesman had my fathers check book in his hand! Disgusting, he was about to sign a cheque for thousands when we got their and asked him to leave.

They called me today from this (780) 486-1363 number.  It was a young lady, you could tell she was younger, probably the only job she thinks she can get, but she can do better than this.  Who wants to work for such a dishonest outfit.  She also told me I had won a prize of I believe $300 in value and that someone had filled out a survey but they need to come to my home and have me do a trial on a product.  Total BS.  No one from my house filled one out because we don't do them, nor when we are out and about either - ever.  She had patently never heard of the National Do Not Call Registry so I shall report the number in a minute although I do appreciate that will not stop these scammers.  I will never do business with dishonest people and I certainly will not let them into my home.  Are you kidding.  No one is ever allowed inside my home unless I know them or they are emergency services.  I did manage to find a number for Zephyr who also advertise  this Eco Health logo here in Edmonton.  Their number is (780) 930-1367.  It amazes me that people would ever do business with these kinds of firms.  Unreal.  Scammers the lot of them.  Don't be fooled and do not let them into your home either because you don't really know who they are and if they have to use such dishonest measure to gain access then beware.  They have no values or scruples.

truly the worst company on the  planet ripping people off, just go online and find ther zephyr for 100 bucks not 3000. nuff said don't be stupid.

If I were you, I would simply keep the unit,just don't answer the phone or the door if it's them close it. They won't take you to court, they will just write it off as a bad debt expense in their accounting

A female sales rep from Eco Air Systems knocked on my 73 year old, mentally unstable, father's door in June. The lady talked him into a air purifier. He told her he could not afford it but she played on his loneliness sitting and smoking with him saying she would come back in 2 days for a visit. My dad unplugged the system and put it back in the box. They have a 10 day return date. He says on the 10th day he was contacted and he let them know he does not like it and to pick it up. Eco Air Systems is claiming it was the 12th day. Thankfully he was able to stop payment through his bank and they have not received a dime. We have still not settled.

The company lies about their product, they say it's good for 3000 sq ft when in reality, its only good for 535 sq ft, contact the manufacturer if you don't believe me.
