Review: Great little device. Easy to install. It is installed on 1" coper line. The water hardness level in my area is 28-30gpg which is extremely hard water. We have a water softener that successfully softens the water but there is a big problem with the amount of salt being introduced to our treated water. So now my water softener is set to a lower number and we get about 7gpg hardness after it (compared to almost none before). Because of the Yarna Descaler the current "harder" water is more manageable now. No more hard white deposits on bathroom or kitchen faucets. The water droplets still leave white powder behind if let dry, but this powder wipes out easy. When I was looking for the descaler I wasn't able to find max flow characteristics for most of the devices, so I opted for the the most powerful device that works with biggest pipe diameter. Maybe it is an overkill for my setup but it works and I'm happy with the result. Review: Bought and installed this per instructions in June 2021. Very easy install. Our well water here near Oshawa, Ontario is very hard, causing extreme deposits on glassware and shower doors. For reference, our original 15-year old salt-based softener works very well, eliminating almost all mineral deposits; it costs about $5-10 in salt a month. Over the next 9 months, ie until March 2022, we ran 4 very controlled A-B comparison cycles between the Yarna and our old salt softener. The Yarna had precisely zero effect. Let me be clear: that's 4 periods with the Yarna, and 4 periods with the salt system. Very thankful Yarna offers a no-questions-asked 1-yr full money-back policy. I'm sure it works for some houses, btw, and the key is extensive testing, so give it a shot. ## Features - Capacitive Electronic ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B085ZYP5JD | | ASIN | B085ZYP5JD | | Brand Name | YARNA | | Capacity | 1 Tons | | Container Type | Faucet | | Customer Reviews | 3.8 3.8 out of 5 stars (287) | | Customer reviews | 3.8 3.8 out of 5 stars (287) | | Date First Available | 17 August 2020 | | Included Components | Installation Kit | | Installation Type | Freestanding | | Item model number | CWD30 | | Manufacturer | Guru Brands LLC | | Manufacturer | Guru Brands LLC | | Material Type | Copper | | Model Name | CWD30 | | Model Number | CWD30 | | Other Special Features of the Product | Chlorine Reduction | | Part Number | CWD48 | | Power Source | Corded Electric | | Product Dimensions | 2.49 x 2.51 x 2.49 cm; 671 g | | Purification Method | Capacitive | | Smart Home Compatibility | Not Smart Home Compatible | | Supported Water TDS Level Maximum (PPM) | 1000 | ## Product Details - **Brand:** YARNA - **Capacity:** 1 Tons - **Included components:** Installation Kit - **Material:** Copper - **Special features:** Chlorine Reduction ## Images ![Capacitive Electronic Water Descaler System - Alternative Water Softener Salt Free for Whole House, Reduces the effects of Limescale [CWD48, Max 4" Pipe] - Image 1](https://m.media-amazon.com/images/I/71yHVjwG1XL.jpg) ## Questions & Answers **Q: Can this be used with a already installed water softener and if so is it better to be installed before or after the water softener?** A: I have a salt water softener on my house hot water supply , and a water conditioner on the hot water heater exit into my house which works well. I have purchased the "Capactive Water Descaler" to put on to the main water in supply into the house, but have not installed it yet, because of the weather. **Q: The pulse waves seem to be moving apart as they form. Is it working? I do not see any results yet :(** A: Thank you for your question. We've made some modifications to the waveform of CWD48. The gaps of the waveform now are bigger compared to the previous one which is thinner and closer to each other. But to further assess your unit, please send us a photo of your display screen showing the waveform. I'm sorry as well that you haven't seen the results yet. The results of using our device depend on many factors like the condition of your plumbing, how thick and hard the existing limescale deposits you have, the pH level of your water, its components and temperature... etc. And these factors vary per customer that's why some may see the results right away, while others may need a few more months to notice the best results. You just need to give the product enough time to work for you. **Q: Will my tds & ec meter still show high hard water readings?** A: It should lower quite a bit. **Q: Can you insulate the water pipes over the bands ?** A: Thank you for your question. Yes, you can still insulate your pipe over the coils/flat bands of the YARNA CWD48 Electronic Water Descaler. We only care that the copper bands are wrapped as tightly to the pipe as possible. That ensures that all the energy generated by the Yarna reaches the water and does what it is supposed to do. You can use any type of insulation over the coils, even the type that has aluminum foil on top. Should you have additional questions, please feel free to message us again. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***I on 25 July 2021* Great little device. Easy to install.

I'll be up front - I thought these things were a scam. But now I'm eating crow ... After just a week the scale in the dishwasher is no more. I had to clean it thoroughly first so that I could see if the device made a difference. But it does! It took about a week to really see the difference in the hot water. Our problem is limestone - calcium - and perhaps that's why it was so effective. I could see the science with that. Kettles still scale up, but MUCH less and it's softer scale that can be easily wiped off. The water is NOT softer of course, but that's not the issue. Would I recommend this? Well I've tried every other none salt based process and overall this will be the most economical and effective - if it lasts. Give it a go, give it a few weeks to try, clean up first, and then see for yourself. You can always return it! Only four stars because of the price. The parts in this device can be purchased for under a hundred bucks if you know where to look. But it seems to be well made and kudos to the company for getting it together! And the money you will save on your appliances will more than cover the cost over time. PS: I should have taken some "before" pics! The inside was thoroughly coated in scale before we installed this and about 70% of it disappeared in a week after installing the device. I then cleaned the dishwasher with citric acid to remove the rest. The pic you see is after three washes. Before the device, the stainless would be grey with calcium deposits after three washes. Now it is not. I have now ordered another unit for another water system that is hard water but NOT strictly limestone. I wonder if it will work as well .... ## Frequently Bought Together - YARNA Capacitive Electronic Water Descaler Whole House Solution - No-Salt Softener System, Reduces Limescale Effects and Mineral Buildup, Compatible with Pipes Up to 4 Inches, Model CWD48 - Varify Water Hardness Test Kit - Water Testing Kit for Home, Drinking, Well, Spa, Swimming Pool, Softener, Dishwasher & More - Hard Water Test Strips for Calcium, Magnesium etc (0-425 pmm, 150 Strips) - YARNA Capacitive Electronic Water Descaler Whole House Solution - No-Salt Softener System, Reduces Limescale Effects and Mineral Buildup, Compatible with Pipes Up to 1 Inch, Model CWD24 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/376648079-capacitive-electronic-water-descaler-system-alternative-water-softener-salt-free](https://www.desertcart.co.th/products/376648079-capacitive-electronic-water-descaler-system-alternative-water-softener-salt-free) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-11*
