First and foremost Atomic Filters is the go-to option when it comes to purchasing replacement filters. I needed a specific filter for my Carrier Air Purifier, one not likely to be available in the big-box stores anyway. I was very glad to find Atomic Filters on the web and will use them as my source going forward. I was especially pleased at how proactive Atomic Filters was in focusing the customer's attention on their website about the subtle changes Carrier made to the filter's item number. While I cannot understand why Carrier felt compelled to add more confusion (by changing the item number anyway), I am glad that Atomic Filters was so forthcoming with the information. One can only imagine how many customers might order the wrong filter absent those warnings from Atomic Filters. I realize that Atomic Filters offers a subscription option but I am not quite ready to jump aboard that train. Carrier obviously recommends changing the filter, something I intend to do. Carrier does not, however, specify rigid recommendations about when to change the filter. In my option, when to replace the filter depends on a variety of factors that can best be determined by the customer, not a distant computer. In any case Atomic Filters has my business.
