ALTHY Auto-Flush Whole-Home Sediment Filter - 40µm Stainless Mesh.

1. Install at main line (indoors): Mount upright on the cold-water inlet after the shutoff valve; connect G3/4" ports (use 1/2" or 1" adapters if needed).
2. Add drain line: Attach the PE hose to the flush outlet and route to a floor drain.
3. Power up: Insert 3×AA batteries in the top compartment; snap the cover closed.
4. Open water, check leaks: Slowly open the main valve; verify arrows match flow direction.
5. Set & forget: Auto-flush runs about every 15 days. Press Flush anytime after plumbing work or visible turbidity.
6. Pair if needed: For taste/chemical removal, add a carbon or RO system downstream—this unit is your sediment first stage.

• Spin-down vortex = first separation: The inlet forms a mini cyclone that throws heavy particles (sand, rust, scale chips) outward, slowing them before they ever touch the screen.
  
• 40 µm 316L stainless mesh = precision intercept: Food-grade 316L (corrosion-proof, heat-stable) stops grit ≥40 µm while keeping pressure drop low. You see the capture through the sight window.
  
• Rotary scraper = self-renewing surface: Line pressure drives a helical rotor that sweeps the mesh continuously, preventing cake-up and keeping pore size true.
  
• Auto-flush valve = hands-off purge: On a ~15-day schedule (or when you tap Flush), the drain port opens; the vortex reverses across the screen and ejects the loaded debris to the hose—no disassembly, no cartridges.
  
• Large-bore, brass head = high flow, low loss: Oversized passages and rigid, lead-free brass unions keep whole-home pressure strong even during high-demand moments.
  
• Why this matters downstream: By stripping abrasive sediment up front, you extend the life of heaters, faucets, dishwashers, espresso/ice machines, and fine filters (carbon, RO membranes), reducing clogs, noise, and energy waste.
  
• Designed for longevity: Reusable mesh typically lasts 2–4 years; housing is BPA-free and tested for 150k water-hammer cycles and high hydrostatic pressure, so the system stays leak-tight under real-world spikes.

• Model: ALTHY AL-PRE-AUTO1 (Whole-home pre-filter)

• Temp Range: 0–40°C (32–104°F) cold-water line only
• Certifications: CE, RoHS
• Use / Position: Household central pre-filtration (before softener/RO/UV)
• Water Sources: Municipal (works as first-stage on many well systems within pressure range)
• Durability Tests: 150,000 water-hammer cycles; 1000 psi hydrostatic burst
• Maintenance: Auto-flush + occasional rinse; mesh typically 2–4 years before replacement
• Do Not: Install outdoors or expose battery compartment to water (avoid short circuit)

In the Box

• ALTHY PRE-AUTO1 Prefilter
• Special wrench
• (2) G3/4" male connectors
• PE drain hose
• User manual

• Indoor use only: Battery bay isn’t waterproof—do not install outdoors or where it can get wet.
• Operating limits: Cold water 0–40 °C (32–104 °F); pressure 0.1–0.7 MPa (1–7 bar). If pressure spikes, use a regulator.
• Freeze caution: Keep above freezing; winterize if the area can drop below 0 °C.
• After line work: Always press Flush to clear construction debris.
• Maintenance: Auto-flush handles routine cleaning; inspect window monthly, rinse mesh if heavily soiled; replace mesh every 2–4 years depending on water quality.
• Drinking water note: This is a pre-filter—it removes sediment, not dissolved chemicals/metals; pair with carbon/RO for full purification.
• Electrical safety: Use fresh AA batteries; avoid short circuiting the battery compartment.
• Fittings: Install upright; use thread sealant/tape on adapters; don’t overtighten brass connections.
  

• Protect your kidneys — reduce grit intake from city lines so every sip is cleaner and easier on your body.
  
• Make coffee gear last longer — shield espresso machines, kettles, and ice makers from abrasive sediment that kills performance.
  
• Cook with pure flavor — boil pasta, rice, and soups in clear water so taste stays clean and consistent.
  
• Healthier daily sips for everyone — kids, pets, and guests get sediment-free water at every tap—no bottles, no refills.
  
• Happier showers & skin — keep shower heads and valves unclogged for a smooth, even, “rain-shower” spray.
  
• Brighter laundry & spotless dishes — cut rust flecks and haze so whites stay bright and glassware sparkles.

☑️ Captures sand and rust down to 40 μm at the main line and auto-flushes the junk out, so your whole home enjoys cleaner, clearer water 24/7.
