Product review (5 stars): Good filters, just $10.00 bucks each higher than two years ago.
last time I bought these in 2014, I paid $25 per filter,  I bought two at that time.  This time I paid $35.50 per filter, and bought two.
Cost of living is going up.  These filter work good and are the best you can buy.  Watch out for the filter made outside of the USA.
