**Short Answer:** **Yes for the machine, but be careful of the "subscription" trap.**
At **$109**, you are getting a $375+ machine at a massive discount (approx. 70% off). However, this machine uses a "razor and blades" business model. While the hardware is cheap right now, the **ongoing cost to run it is high** compared to standard filters because you **must** buy their proprietary mineral packs.
If you want a high-end RO system that makes hot tea/coffee instantly and don't mind paying premium prices for the water itself (~$0.45/gallon), it's a steal. If you want cheap filtered water, this is not the right device.
***
### **Cost Breakdown**
The initial price is low, but the maintenance costs add up quickly.
#### **1. The Machine**
* **Current Price:** $109.99 (Woot)
* **Regular Price:** ~$375 - $400 USD [1][2]
* **Verdict:** Excellent entry price.
#### **2. Replacement Filters (The "Hidden" Cost)**
* **Cost:** Approx. **$100 - $110 USD** for a set [3][4].
* **Lifespan:**
* **Sediment/Carbon Filter:** 1 year or 1,500 Liters (~396 Gallons).
* **RO Filter:** 2 years or 3,000 Liters (~792 Gallons).
* **Availability:** These are proprietary. If the company (Lang) stops shipping to the US or goes out of business, the machine becomes useless.
#### **3. Mineral Packs ("Langpaks") - The Real Cost**
* **Cost:** Approx. **$30 USD** for a set of minerals [5][6].
* **Yield:** One set treats about **250 Liters (approx. 66 Gallons)** [7][8].
* **Cost Per Gallon:** Roughly **$0.45 per gallon** just for minerals.
* *Comparison:* A standard Brita filter costs about $0.15/gallon to run.
***
### **Critical Questions Answered**
#### **"Do you need the minerals or can you do it without?"**
**You NEED the minerals.**
According to the manufacturer's FAQ, the machine is designed to **not work without them** [9][10].
* **Reason:** Reverse Osmosis (RO) removes *everything*, making water acidic and flat-tasting. The machine adds minerals back in for taste and health.
* **Constraint:** The system likely uses the mineral pack insertion as a key to operate. You cannot simply skip this cost.
#### **"How many gallons can you make before changing the filter?"**
* **RO Filter:** ~792 Gallons (3,000 Liters) [2].
* **Pre-Filter:** ~396 Gallons (1,500 Liters).
* **Minerals:** ~66 Gallons (250 Liters) per pack.
* **Note:** You will buy roughly **12 packs of minerals** ($360) before you need to replace the main RO filter.
***
### **What do the reviews say?**
**Rating:** Generally **3.8 out of 5 stars** [11].
| **Pros (The Good)** | **Cons (The Bad)** |
| :--- | :--- |
| **Taste:** Users universally praise the water taste as "undeniably superior" and crisp. | **Not Cold:** The "Cold" setting is often described as "cool" or "room temperature," not ice cold [11]. |
| **Hot Water:** The instant hot water feature is excellent for tea/coffee lovers. | **Small Tank:** The reservoir is small, requiring frequent refilling (a "nuisance") [11]. |
| **Design:** It looks sleek and modern on the counter. | **Slow Flow:** It takes about 2.5 minutes to make 1 Liter of water [8]. |
***
### **Questions You Forgot to Ask (Buyer's Checklist)**
As a buyer, here are the "gotchas" you should consider before pulling the trigger:
1. **"Can I buy filters in the US easily?"**
* *Answer:* Availability is spotty. Most links go to European sites or a specific US Shopify page (`shop.drinklang.us`). Since this is on Woot (often a clearance site), ensure you can actually buy a 1-2 year supply of filters *now* if you plan to keep it.
2. **"Does it waste water?"**
* *Answer:* Yes, all RO systems waste water. This unit has a roughly **2.3:1 efficiency ratio** (it wastes about 1 cup of water for every 2.3 cups it makes), which is actually very efficient for a countertop RO system [8].
3. **"Is the water truly cold?"**
* *Answer:* No. If you want ice-cold fridge water, this will disappoint you. It uses a "Peltier" cooler which is quiet but not very powerful.

However, at $30 for Mineral A+B packs which only last 250 mL, you will need 12 of these before you change out the RO filters ($100). It might still be cheaper and better than Brita.
That is $360 + $100, or $460 in mineral packs and RO filters over 2 years. Pretty expensive compared to a traditional RO system like the APEC RO system (7 stages) which is about $100/yr for filters. But the APEC requires plumbing and space under the sink to hide the tank and a faucet to dispense the RO water. And the upfront cost of the ROES-PH75 is $268.

Did not expect minerals would be sold out.
