Excellent product and great customer service. I ordered the IQ Air Health Pro 250 Air Purifier as I live on a busy road and my house is quite dusty from some recent renovations which triggered my asthma. I’ve had the IQ Air Purifier for a couple of days now and the air has dramatically improved and I can now sleep much better and the air feels much fresher in my home. The customer service was excellent and I received a phone call shortly after placing my order to arrange delivery. They also offered to come to my house and set it up and they did some air quality monitoring during their visit. The guy who attended unpacked everything and set it up so it was working straight away. Allergy Cosmos were able to answer all my technical questions and the communication was excellent. Would highly recommend the product and the customer service. Although the Air Purifier is expensive, it’s well worth the investment and the health benefits in my opinion.
