Description
This 5-micron string-wound polypropylene sediment filter is the factory-specified pre-filter replacement for Hydrotech reverse osmosis systems, compatible with the 1240 Series (E, M, and Pro), HT101, HT102, HT103, and HT123 Series systems. As the first line of defense in your RO system, it captures dirt, rust, sand, and suspended particles down to 5 microns before water reaches the membrane — protecting it from premature fouling and extending its usable life.
Due to its role as the primary sediment barrier, this filter works harder than downstream stages and should be replaced every 3 to 6 months to maintain proper flow and system efficiency. Its candle-mount connection is proprietary to Hydrotech systems, making replacement simple and tool-free.
- Reduces sediment particles, including dirt, rust, and sand, down to 5 microns
- Pre-filter for Hydrotech 1240 Series (E, M, Pro), HT101, HT102, HT103, and HT123 RO systems — protects the membrane from premature wear
- Candle-mount connection fits directly into compatible Hydrotech systems
Specs
- Dimensions: 11.5" X 1.875"
- Replace every 6-12 months

Sediment filter
"This filter has our water system running at its highest capacity since installed. Great product."
Just the right filter
"As everyone does, I shopped around and found all the filters I needed for our RO system. The ESP Water site had all the products I needed for the RO system. The site was very easy to use and precise pictures to see the products. The filter was exactly the right one for my system at a very competitive price. Look no further this is the right place to shop. Order from your sofa and voila it's in your mailbox and drink away !!"

Q&A
Q:
Which systems use Hydrotech 41400008?
A:
The catalog lists Platinum 1240; 1240 M and Pro; 4VTFC09G (1240200-00); 4VTFC25G (1240201-00); 4VTFC25G-PB (1240301-00); 4VTFC50G (1240202-00); 4VTFC50G-PB (1240302-00); 4VTFC75G (1240203-00); 4VTFC75G-PB (1240303-00); and 4VTFC9G-PB (1240300-00). Match the existing part number and candle-mount connection.
Q:
What does the 41400008 reduce?
A:
The nominal 5-micron string-wound polypropylene media captures dirt, rust, sand, and other suspended particles before they reach downstream filters and the RO membrane.
Q:
Is this a standard 10-inch sediment cartridge?
A:
No. It measures about 2 inches by 11.5 inches and uses a Hydrotech candle-mount connection. Confirm part number 41400008 or S-FS-02.
Q:
How often should the 41400008 be changed?
A:
A typical interval is about every six months, or sooner when reduced flow or source-water sediment indicates loading.
Q:
Why can a loaded prefilter reduce RO performance?
A:
A loaded sediment stage restricts feed flow and pressure to the membrane, which can slow production and tank refill time.
Q:
Can a generic 2.5-by-10-inch filter replace it?
A:
No. A generic drop-in cartridge does not match the candle-mount connection or dimensions. Use a replacement specifically cross-referenced to 41400008.
