How the 5-Stage Filtration Works
| Stage | Media | What It Targets | Why It Matters |
|---|---|---|---|
| 1 | Sediment membrane (0.5 µm) | Rust, sand, fine particulates | Protects downstream media, improves clarity |
| 2 | Sediment membrane (0.5 µm) | Remaining fine particles | Enhances overall filtration and taste |
| 3 | KDF‑55 (copper-zinc alloy) | Lead, chlorine, certain heavy metals | Helps reduce metals and chlorine; bacteriostatic properties |
| 4 | Activated carbon | Chlorine, VOCs, taste/odor compounds | Major taste and smell improvement |
| 5 | Activated carbon (polishing) | Residual tastes/odors | Smoother finish and better mouthfeel |
Important note: This filter does not reduce TDS (total dissolved solids). That’s by design—minerals like calcium and magnesium remain, which many people prefer for taste. If you need very low TDS or broad-spectrum dissolved solids removal (including fluoride), consider a reverse osmosis (RO) system instead.
Performance in Daily Use
- Taste and Odor: If your tap water has a chlorine smell or flat taste, the V7’s dual carbon stages and KDF‑55 media are engineered to deliver noticeable improvement.
- Lead and Chlorine Reduction: SimPure states up to 99% reduction of lead and chlorine. Always verify claims and review certifications on the product listing if you need compliance for specific standards.
- Flow Rate: At up to 1.6 GPM, the V7 keeps your main faucet feeling fast—great for rinsing produce, filling pots, and general cooking without switching to a trickle.
- Mineral Retention: Keeping calcium/magnesium makes water taste “natural,” while the filter targets the off-flavors and common contaminants associated with municipal water distribution.

Installation: Truly No-Drill, Renter-Friendly
SimPure designed the V7 for a quick, do-it-yourself install:
- Shut off the cold water under your sink.
- Disconnect the existing cold-water line from the faucet.
- Insert the V7 in-line using the included 3/8″ or 1/2″ adapters.
- Hand-tighten, then snug with a wrench—don’t overtighten.
- Turn water back on and check for leaks.
- Flush for several minutes to clear initial carbon fines.
Because it connects to your main faucet, you get filtered water everywhere your cold tap flows—no holes to drill, no second faucet, and no counter clutter. This is ideal for renters, RVs, or anyone who wants a clean setup with minimal tools.
Tip: Keep plumber’s tape handy and always verify a dry connection after install. If you’re unsure, consult a professional.
Build Quality and Safety
- Stainless Steel Housing: The 304 stainless body resists corrosion, impacts, and pressure better than typical plastic housings—peace of mind in a high-use kitchen.
- BPA-Free Materials: All water-contact components are food-grade.
- Leak Resistance: The robust canister and fittings are designed to minimize leak risk when properly installed.
SimPure has been serving U.S. customers from Seattle, WA, since 2006, and offers support if you have questions during setup or use.
Maintenance, Longevity, and Cost
- Filter Life: Rated for up to 20,000 gallons or about 12 months. Your actual interval will depend on usage and water quality. Expect earlier replacement if sediment levels are high or flow noticeably declines.
- Replacement Availability: You’ll find replacement options on the product page; plan ahead and keep one on hand to avoid downtime.
- Operating Tips:
- If your water is very sediment-heavy, consider an inexpensive pre-filter to prolong life.
- Replace sooner if taste/odor returns or flow drops materially.

Who It’s Best For
- Renters and homeowners who don’t want to drill or add a separate faucet
- Busy kitchens that want filtered water at full flow
- Municipal water users focused on cutting chlorine, taste/odor, and lead
- People who prefer minerals left in the water (no TDS reduction)
- Light RV or condo use where space and simplicity matter
Who should consider alternatives:
- Households needing very low TDS or fluoride removal—look at RO systems
- Private well users concerned about microbiological contaminants (this is not a purifier; test and choose treatment accordingly)
- Those who require specific certifications for regulated contaminants—verify the exact standards listed on the product page
Comparisons: V7 vs Common Alternatives
- Reverse Osmosis (RO): RO removes a wider array of dissolved solids (including fluoride) and typically lowers TDS, but wastes some water, runs slower, and often requires a tank and a drilled faucet. The V7 is simpler, faster, and retains minerals.
- Pitcher Filters: Easy and inexpensive, but slow and low-capacity, with frequent cartridge changes. The V7 delivers whole-faucet convenience and much higher flow.
- Faucet-Mount Filters: Easy to install but often bulky, with lower flow and shorter lifespans. The V7 hides away and serves the entire cold-water stream.
Pros and Cons
Pros
- 5-stage, 0.5‑micron filtration stack with KDF‑55 and dual carbon
- Up to 1.6 GPM high flow—no more waiting at the sink
- Long 20,000‑gallon life (up to ~12 months)
- No drilling or separate faucet required
- 304 stainless steel housing, BPA-free materials
- Fits 3/8″ and 1/2″ lines with included adapters

Cons
- Does not reduce TDS; if you want very low TDS or fluoride removal, go RO
- Designed for municipal water; not a microbiological purifier
- Replacement intervals vary with local water quality
FAQs
- Does it remove fluoride?
- No. Carbon/KDF filters like this generally do not remove fluoride. Consider RO or activated alumina media for that need.
- Is it “squat-proof”—er, we mean leak-proof?
- The stainless housing is robust and resistant to leaks when installed correctly. Always check connections after install and periodically thereafter.
- Will it fit my sink?
- It connects to the cold-water line, not the faucet spout. It includes 3/8″ and 1/2″ adapters to fit most U.S. setups.
- How do I know when to replace the filter?
- Changes in taste/odor, reduced flow, or reaching the rated gallons/time interval are your cues. Some users also keep simple chlorine test strips to monitor performance.
- Is it certified?
- SimPure states the V7 is certified to reduce lead, chlorine, and taste/odor. Check the Amazon listing for the exact standards and documentation if you need a specific certification.
Final Verdict
If you want a straightforward, renter-friendly under-sink filter that keeps your main faucet fast while cutting chlorine, lead, and off-tastes, the SimPure V7 is an excellent value. Its stainless-steel build, 5-stage 0.5‑micron stack, and direct-connect install make it a compelling alternative to bulky RO systems or slow pitchers—especially for households that prefer mineral-rich water and minimal maintenance.
