Premium filtration
RED COLOR - PREMIUM FILTER
This RED premium filter has more consistant density than our standard blue filters. The 36 pack is a great value for all users.
NOTE:
Two filters should be stacked on top of each other for extra protection.
TIP:
Top filter should be changed weekly. Just discard the top one, rotate the bottom one up and put a fresh one on bottom. Double filtration with no additional cost!
