Lo-Chlor Instant Filter Cleaner is a non-soak spray-on formula for cleaning pool and spa cartridge filter elements — removing oils, minerals, calcium and biological debris in a single application without overnight soaking.
Traditional cartridge filter cleaning requires soaking the filter element in a cleaning solution for hours or overnight before rinsing. Instant Filter Cleaner's non-soak technology penetrates the filter media immediately, breaking down deposits on contact and allowing the filter to be back in service within an hour — dramatically reducing pool downtime.

🔍 Is it right for my filter?▾
Instant Filter Cleaner is designed for cartridge filter elements.
🔵Cartridge filter▾
✓ Primary use — cartridge filter elements
Designed specifically for cartridge filter elements. Spray evenly over the full filter surface, allow 5–10 minutes, rinse thoroughly with a hose.
🌊DE (diatomaceous earth) filter▾
✓ Compatible with DE filter grids
Can be used to clean DE filter grids when removed for servicing. Rinse thoroughly before recharging with DE powder.
🏖Sand filter▾
✗ Use Enviro-Clean for sand filters
Sand filter media does not benefit from spray-on cartridge cleaner. Use Lo-Chlor Enviro-Clean for sand and glass filter media.
🛁Spa filter cartridges▾
✓ Ideal for spa filter maintenance
Spa filter cartridges accumulate oils and body products rapidly. Clean every 2–4 weeks for spas in regular use.
💧All pool types▾
✓ Works regardless of sanitiser system
Compatible with all pool chemistry — chlorine, salt, PHMB (AquaFresh/AquaSpa) and mineral systems.
🔩Heat exchanger heads▾
⚠ Check manufacturer guidance
Some heat exchanger components can be cleaned with this product, but check the manufacturer's guidance before applying to internal heater components.
💊 How to use▾
Remove filter cartridge from housing before cleaning. Clean outdoors if possible.
Standard clean
Spray evenly
then wait 5–10 min
Lay filter on its side. Spray evenly from top to bottom, rotating filter. Allow 5–10 minutes, then rinse with a strong hose stream.
Heavy fouling
Two-pass application
For filters with heavy oil or calcium buildup, apply a second coat after the first rinse. Allow contact time and rinse again.
Cleaning frequency
Every 3–4 months
or when pressure rises
Replace or clean the filter when system pressure rises 10+ kPa above the clean baseline. Don't wait until the pool is cloudy.
Replace when worn
Inspect for damage
while cleaning
Each cleaning is an opportunity to inspect for cracked end caps, torn pleats or collapsed cores. Replace any damaged elements.
❓ FAQ▾
How often should I clean my cartridge filter?▾
Every 3–4 months under normal residential use. Spas need more frequent cleaning (monthly). The best indicator is rising system pressure — clean when pressure rises 10 kPa above the clean baseline or when flow visibly decreases.
Can I put the cartridge back immediately after cleaning?▾
Yes — that's the key advantage of the non-soak formula. Once rinsed thoroughly, the cartridge can be reinstalled and the system restarted. Allow the rinse water to run clear before reinstalling.
How many cleanings does a 500ml bottle provide?▾
Depending on filter size and fouling level, a 500ml bottle typically provides 3–6 cleaning cycles for a standard residential pool filter cartridge. Smaller spa filters require less product per clean.
