Easy Replacement
Easy to replace, but the old filter was a little difficult to remove. Overall, these filters make an RO system much easier to maintain than the tank based system I used before.

Working well for RMS-WP-RO400
I bought a RMS-WP-RO400 unit last year and the company does not have any replacement filters for sale (although I would imagine there filters for the RO500 would work). This appears to be working well in the old unit.
