Product review (5 stars): They make it easy.
This is a much-more affordable alternative to the name-brand and I can't tell a difference in performance. Date stickers come with the product so you can label the filter with the install date; no need to write the date. I also appreciate how, once you place an order for this product, the vendor will send an email reminder that the time is near to replace the filter. This saves me the added step of having to go back six months in my order history to re-purchase. They make it easy.
