Review on Deionization Reverse Filtration System by Express Water by Jaleel Pruitt

This kit gives you a lot of features for the price but I would recommend this kit instead: https://www.amazon.com/dp/B00J2DGTD8/ref= emc_b_5_t Below I will explain why. First of all, I really like this set. This kit contains everything needed for a standard installation. It has an automatic shut off when the tank is full, which is a key feature as without this shut off valve these units can generate around 300 gallons of waste water per day. Second, it has two stages of carbon filtration in front of the reverse osmosis membrane. It takes a bit to figure out why that's good, but it ends up talking about chloramine-treated water, which many cities use because it's more stable than chlorine. This stability also means it is more difficult to remove, requiring multiple carbon steps. I'm not 100% sure what the third carbon stage adds, other than that it's nice to have and a post membrane scrubber can remove some of the unwanted chemicals that might leach out there. Overall, I don't hate the third carbon tier, but I don't know if I'd bother adding it, but it's a nice feature that I'm excited about. I would change two things about this kit: First, I would add a diaphragm purge valve. This allows you to "bypass” the reverse osmosis membrane and only produce waste water. This is key to replacing the first two stages of carbon and also a good preventive maintenance step that should be performed regularly to prolong the life of your reverse osmosis membrane. You can buy this separately for around $10 and it will be a good investment. This isn't a deal breaker though, I really like this reverse osmosis unit (warning no DI unit). The reason I would recommend a different kit is because I highly recommend you skip this deionizer. If you don't need a deionizer, don't waste your money. Not only does this add about $30 to the filter cost, it also increases the filter media by about $80 per year ($40 for a filter change every 6 months). As far as I can tell it is an inline dual media filter that needs to be replaced when media is depleted. It's hard to know if and when you'll need to replace the media (no clear container of color-changing media), and replacement media is very expensive. For about $100 you can get a two-stage deionizer with a standalone (on/off) TDS meter, color-changing media that lets you know when the media needs to be replaced, and two separate deionization media that only swap out when used and the medium is only about $15 for a replacement canister ($30 for a full replacement) and should last twice as long. This upgrade should easily pay for itself in the first year. Additionally, an optional TDS meter lets you know when the input TDS starts to rise, indicating a diaphragm failure. It's cheaper to replace a defective $17 cone than it is to destroy a $30 carrier just to replace both. This feature will save you about $20 on your first membrane change. All in all a fantastic set. You get a lot for the price and the quality seems fantastic, but I would choose another kit from the same manufacturer and pay a little more up front for a custom dual state DI filter with color changing.
