Will this fit the new Dolphin Nautilus with cleaver clean? Every write up I've seen said it is for the Dolphin Nautilus Plus but I am wondering if the new Dolphin Nautilus has the same basket configuration as the Plus. Thanks!

Hi, Adam. The Nautilus and Nautilus Plus does not use the same cartridge configuration. The Nautilus unit uses p/n 9991425-ASSY

When should you replace filter cartridges we have the m5 dolphin fine filters?
 Reply

A  Answered on 10/23/2017 by InyoPools Product Specialist Lennox H.

Hi, Lisa. Depending on often the unit is used, these filters will need to be replaced every six months or so.

Lisa, I have had the M5 for 4 years and used the #9991432-ASSY (Ultra Fine filter) exclusively. If you take the filters out each time you use it and clean them very well with jet nozzle of your hose they will last a long time. I have not changed the filters in 4 years and they still work great. The serert is Clean, clean clean them EACH time you run the Dolphin.
