Provides perfect water

I've had my new hot tub with salt generator running for a few weeks. Dealer recommended Spa Marvel enzyme conditioner and I also purchased the X10 filter. PH, alkalinity and hardness were all perfect at initial fill using the X10 filter. After  adding a small amount of initial base chlorine and the recommended salt, the generator has been providing perfect sanitation. I did add the Spa Marvel conditioner but no other chemicals so far. Daily balance readings have remained perfect without need for additional balancing. I've added a little filtered water to replace evaporation loss but negligible effect on salt level. It's worked great for me. I know some recommend using a portable water softener in salt system but my calcium levels are at what my spa manufacturer recommended.

Does The Job

Unlike previous filters I’ve used, this one doesn’t slow down the flow much.  We have water that’s high in metals and this filter does a nice job of pulling them out.  It’s easier to get the water adjusted after using this during each fill up.

Excellent for filling a hot tub

This is one of the best filters I have used when filling up my hot tub.  Would highly recommend using it when doing your water change or topping up your hot tub.

Softens the water

A little pricey but it does what it needs to use it for a wood burning hot tub and we noticed the water is on lot softer I will be buying one every year

Easy to use

It really is a time saver.


Ask a Question
  • The filter says max limit is 2gpm. Is that the max it can filter effectively? The water from the hose through the filter is much higher than 2gpm.

    The X10 filter actually will slow the water gpm to 2 gpm to filter effectively. If you would like to go faster, you can put a splitter on the hose and use 2 filters getting you up to 4 gpm and so on.

  • What happens if the filter dries out?

    When the filter dries out, the KDF media in the filter is no longer activated. It's very important to store the filter with some moisture inside. End caps are provided with the filter to prevent it from drying out. If you lose the end caps, use a resealable storage bag instead.

  • Is there any way to tell when you have reached the 10,000 gallon limit? I use it currently for makeup water for a swim spa.

    Thank you for your question. You will know when the X10 has reached it's limit because the sediment trapped inside the filter prevents water from flowing through it. You can put a tick mark on the case of the filter each time you use it and if you know approximately how many gallons you put in to top up the swim spa, take the 2 numbers and multiply them together to get an estimate of the total gallons filtered. 

  • Hello could you please tell me if your X10 WATER FILTER filters bacteria and if so how many microns does it filter?

    The X10 Filter primarily works differently than how most filters work, by utilizing a media called Kinetic Degradation Fluxion (KDF).  The media works to reduce or remove chlorine, iron, hydrogen sulfide, lead, mercury, calcium carbonate, magnesium, chromium, bacteria, algae, and fungi.  The KDF media exchanges electrons with contaminants, changing them into harmless components. During their reactions, electrons are transferred between molecules and new elements are created.


    With respect to bacteria specifically, KDF media kills bacteria by direct electrochemical contact and by the flash formation of hydroxyl radicals and hydrogen peroxide, both of which interfere with a microorganism's ability to function.


    Having said that, the X10 does also have a 50 micron filter, but it is mainly to collect sediment and other larger particles that may be in the water.


    While KDF does a great job at killing bacteria, we do not purport that the X10 Filter is a device to make water microbiologically safe.
