How do I know which replacement filter I need?

Start by checking your system brand and model number. Then match it to the compatible replacement filter, membrane, or kit listed on the product page. If you are unsure, send Stratus Water Systems a photo of your system or existing filter and we can help confirm compatibility before you order.

What brands and systems do you support?

Stratus Water Systems carries replacement filters, RO systems, membranes, and compatible parts for brands including IntelliClear®, ProLine®, RORO®, Clack®, and other water filtration systems. Availability may vary by product and system type.

Are your filters genuine replacement parts?

Stratus Water Systems carries genuine replacement filters, systems, and components from trusted water filtration brands. Each product page includes details about the brand, system fit, and compatibility so you can order with confidence.

How often should reverse osmosis filters be replaced?

Most reverse osmosis pre-filters and post-filters are replaced every 6 to 12 months. RO membranes typically last 12 to 24 months, depending on water quality, usage, and the specific system. Always check the recommendation for your exact model.

Can I replace my water filters myself?

Many residential RO systems and filter kits are designed for simple replacement. Some systems use twist-in cartridges, while others may require shutting off the water supply and depressurizing the system first. Always follow your system instructions or contact us if you are unsure.

Do you ship from the USA?

Yes. Stratus Water Systems ships from the USA, with fast processing on in-stock replacement filters, RO systems, membranes, and compatible water filtration parts.
