Car Wash Spot-Free RO Slim Pleated Pre-Filter Case – 25 Pack – 5 Micron – 20" x 2.5" – Fits ECP5-20, EQ-304-20

A full case of 25 pleated 5 micron sediment pre-filters in the 20" x 2.5" slim size used on compact and wall-mount car wash spot-free rinse RO units, detailing rigs and window-washing water systems. Pleated media gives far more surface area than a spun cartridge of the same size, so it lasts longer between changes and keeps pressure drop low ahead of the RO membrane.

Why car washes buy the case

• Change the sediment pre-filter at least every 90 days; one case covers a single slim housing for about 6 years or a multi-housing system for a season
• Case pricing far below single-filter pricing
• Ships in one sealed carton, so spares stay clean on the shelf
