Description
This 5-micron string-wound polypropylene sediment filter is the factory-specified first-stage replacement filter for Pura and Aqua Flo UV20 ultraviolet disinfection systems. Designed to work upstream of both the carbon block and UV chamber, it captures sediment particles, dirt, rust, and debris before they can reach and foul the downstream filtration and disinfection stages — preserving the performance and lifespan of your entire system.
Keeping this filter replaced on schedule every 6 to 12 months is essential to maintaining proper flow and protecting the carbon block and UV lamp from premature wear. Installation fits any standard 20" sump housing with no modifications required. Refer to your UV20 system manual for complete installation guidance.

"I appreciate the help that I got. The filter was just what I needed."
Great company.
"The customer service at ESP is wonderful. I talked to someone who took a real interest in my situation -- I felt like I was talking to the head of the company! The filters I ordered arrived at my door in just a few days. The filters fit the housing I have and do a good job of filtering the spring creek water to the cabin. Thank you!"
Q&A
Q:
Which systems use the Pura 36161 filter?
A:
The catalog lists UV20, UV20-2 SD, and UV20-3 systems. Confirm the exact model and the 2.5-by-20-inch cartridge size before ordering.
Q:
What does the 36161 reduce?
A:
The 5-micron string-wound polypropylene cartridge reduces dirt, rust, and suspended sediment before the carbon and UV stages.
Q:
What size housing does it fit?
A:
It measures 2.5 inches by 20 inches and fits a standard 20-inch slim sump housing. It will not fit a 10-inch housing.
Q:
Why is this filter placed before the UV chamber?
A:
It limits particulate loading on the downstream carbon cartridge and UV chamber, supporting the system's intended flow and treatment conditions.
Q:
How often should the Pura 36161 be changed?
A:
A common interval is 6 to 12 months, but heavy sediment or declining flow can require earlier replacement.
Q:
Does the 36161 reduce chlorine taste and odor?
A:
No. It is a sediment cartridge. The UV20 system uses a separate carbon stage when chlorine taste and odor reduction is required.
