Whole house filter. I thought 30 microns would last longer than 5 microns AP810 (3-4 months). The horrible pleated filter became clogged within 1-1-1/2 weeks and severely restricted flow. I would like to send them back for verification. Back to AP810 or AP811 (25 Β΅m). Grooved filters do not cost anything, they need to be changed 8-10 times more often.
