Product review (1 stars): Poor fitment and confusing instructions.
2 concerns: 1) the handle the slides into the filter for installation for poorly and loosely and 2) the instructions say to use the filter within 30 days of receiving the filter. The Second concern really confused me because this is a multipack product and each filter is good for at least 90 days. If this were true then the other two unused filters would expire before the first used filter needed to be replaced.
