Bests & Worsts Reviews from Amazon

This did not make a difference after 2 months of use. After one month of use in a 10' X 13' room no difference. After a week of use I did not notice any changes and thought I may need more. Amazon only sales single units, so I went to the Clarifion website and bought 6 for a discounted price. I bought some "Brilliant Evolution Bamboo Charcoal Air Purifying Bags" on Amazon and they did a much better job. I tried to cancel the second Clarifion order, but was emailed that It had been shipped even though it had not been delivered to USPS. I recieved the direct order after 62 days and am still tring to return them.
