“I bought the IQ Air 250 from Allergy Cosmos around 2 years ago and I've had no issues with it at all. The replacement filters are easy to order online and they arrive the next day. I've not had to deal with their customer service team but if it's as good as their products then that should be great to.”

“I have been ordering my filters for my BlueAir511 air filter through Allergy Cosmos for a while now. Ordering is easy, fast delivery and the quality of the filter replacement is fabulous. Love this company as they make ordering replacement filters so easy and they send you a reminder email just before your filter is due to need replacing. Thank you Allergy Cosmos.”

“I came across Allergy Cosmos, when searching for an IQAir dealer. I had been interested in the HealthPro 250, but I was also considering the Atem X. I spoke to Jayson Cook, who gave me a thorough explanation of the technical differences between the two models, their application in my particular setting, the cost of filters, and a comparison with the other main brand they sell. He was not pushy at all, and gave the immediate impression of someone with excellent knowledge of this subject, and whose advice one could trust. I decided to purchase the Atem X, which arrived the following day, in an extremely robust manufacturer's box, which had a couple of handles to turn on the outside, so as to be able to release it, which I think were to prevent movement in transit. I recommend this company without hesitation.”
