Duneach, Dark Red

Much better than cheaper corrugated filters, but on one batch the retaining plastic mesh developed a tear.

I have been using the Silver Sentinel in my Arctic tub for about a year now and it works great. The filter combined with some non-chlorine oxidizer keeps my tub clean and balanced. For years I used standard filters which I cleaned and rotated 1x per quarter. Unfortunately, the chemicals used to clean the filter also upset the PH of my tub. With this filter I just swap it with a new one every 3-4 months and my PH stays perfect all the time. Great product so far - will save you $$ on PH and Alkalinity chemicals so worth the money.

I was hoping to get this filter a little less than in the spa stores, but it's really worth the money. Since there is no maintenance to the filter, just adding a little chlorine or bromine, it makes life easy. I just needed to remind myself to change the filter every 3 months or so depending on the use. Also great on cutting down on the amount of chemicals needed!

This filter fits my hot tub very nicely

I have an older arctic spa n switched the filter out with this one ....works great and cleared up my water as intended. I was getting some top of the water floating debris from it being an outside hot tub that wouldn't go away but it's cleared up now!

have ordered these filters for many years with satisfactory results. However, realizing that competitiion has better options at this upgrade point in my life.......different proposition DN is not considering.

Exactly what was advertised and the price was good. Fit our spa perfectly.

Nice, glad I bought it...
