Review on WAGNER Switzerland Replacement Cartridge Purifiers by Calvin Reynolds

Advantages and disadvantages of the filter: Pros: - suitable for Wagner WA888 and Lemarc WA888G - reduces pollen count and helps to reduce allergies Cons: - expensive filter with a low carbon content. When I shake the filter to hear activated carbon, I hear a lot of void space. When I tore it apart I saw that it was less than 50% filled with carbon. Not very good for removing odors and smoke. See attached photos for reference. I have found that I can make my own filter at a lower cost using a quality 14"x20" Merv oven filter. Any brand is suitable, and a pleated filter (corrugated fabric) is better to increase the surface area. Cut it in half measuring 14" x 10" which is roughly the size of the original filter and tape the cut end. By wrapping a 1 inch piece of cut cardboard around the cut edge of the filter you can stiffen the end of the filter if the filter is too soft. Take a roll of universal charcoal filter and measure approximately 14 x 10 inches, cut a sheet of charcoal and lay it out. Then glue the edges of the carbon filter to the edges of the merv filter. Instant DIY filter for about $12 for 5-10 minutes, and it does a better job of removing smoke and odors because the carbon is evenly distributed over the entire surface. Filter.
