New Filter Names and Descriptions are Coming

We are excited to announce an update to the names and descriptions of our existing filters. After listening to customer feedback, we learned that it can often be a confusing process to understand which filter is right for your specific needs. To help alleviate those concerns we are introducing new names, descriptions and a comparison chart to give you the information and confidence you need to find the filter for your space. The Pure filter now becomes the Essential filter. The Fresh filter becomes the Advanced filter and the Odor filter is now the Ultimate. (*Please also note that the VOC/Smoke filter has been discontinued with the Advanced filter being its replacement.) You can find the details of these three filters in the comparison table as well as within the descriptions below.
