RO Water Filter Model Selection Guide – Choose 112‑115

Quick Recommendation

If your household uses up to about 80 gallons of water per day, the DREO RO Water Filter 113 offers a balanced capacity and smart monitoring. For lower usage, consider model 112; for higher demand, models 114 or 115 may be a better fit.

Choosing the right RO water filter model hinges on how much water your home consumes each day. DREO’s 112‑115 series shares core RO technology, but each model varies in tank size, filtration speed, and smart features.

This guide walks you through the key factors—daily usage, filtration capacity, and cost—so you can apply a practical decision framework without guessing or over‑paying.

Understanding Daily Water Usage

Start by estimating your household’s average daily water draw. Count drinking, cooking, and basic appliance use. A typical family of four uses roughly 60‑80 gallons per day, while a single‑person apartment may stay under 30 gallons.

Knowing this number lets you align it with each model’s rated capacity. DREO does not publish exact daily throughput for models 112, 114, and 115, so you’ll need to rely on the general capacity tiers that the brand markets: low, medium, and high.

• Measure usage for a full week for the most accurate average.
• Add a 10‑15% buffer to accommodate occasional guests or extra cooking.

Capacity and Filtration Performance

Model 113, the mid‑range option, balances a sizable tank with a smart indicator that shows real‑time TDS levels. This helps you know exactly when the filter needs replacement, preventing over‑use.

Higher‑capacity models (114/115) typically feature larger tanks and faster flow rates, useful for larger homes or heavy‑use kitchens. Lower‑capacity model 112 is compact and cheaper but may require more frequent filter changes in busy households.

• If you need continuous hot water for cooking, lean toward the larger‑tank models.
• For space‑constrained setups, the compact 112 fits better.

Cost vs. Feature Trade‑offs

The price gap between the models reflects tank size and smart‑monitoring hardware. Model 113 is priced at USD 100 with a comparison price of USD 199.99, offering good value for most families.

Investing in a higher‑capacity model only makes sense if your daily usage consistently exceeds the mid‑range threshold. Otherwise, you may pay extra for capacity you never use.

• Consider the total cost of ownership: filter cartridge lifespan and electricity for any built‑in pumps.
• Smart indicators add convenience but are optional for users comfortable with manual checks.

Decision Rules for Selecting Your RO Filter

• Assess Daily Usage: Calculate average gallons per day and add a 10‑15% safety margin. Match low (80 gal) usage to models 112, 113, or 114‑115 respectively.
• Check Filter Capacity & Smart Features: Review tank size, flow rate, and whether real‑time TDS monitoring is needed. Choose model 113 for balanced capacity and smart alerts; skip smart features if you prefer manual checks.
• Consider Total Cost of Ownership: Factor in upfront price, filter cartridge lifespan, and any optional accessories. Avoid over‑paying for high‑capacity models unless your usage truly exceeds the mid‑range threshold.
