First-time installers, or anyone swapping out an older sediment filter, usually want the 3/4 port version — it's what fits most standard houses without needing an adapter, but we do suggest checking your current pipe diameter before ordering.

Water Filter Housing

We've got roughly 200 units in stock right now, so lead time is about a week or so, and they ship in either a color box or plain carton depending on teh MOQ — the steel bracket and wrench are included, which saves you a trip to hardware store.

Water Filter Components

What it does is trap sediment and reduce chlorine taste through activated carbon, but it's not for direct drinking — you'll still need a main purification system downstream for that, and basically if your water temperture runs hot, this isn't suited for it since there's no descaling function.

Filter Installation

The port sizes (1/2, 3/4, and 1 inch) are pretty standard, and the incremental pipe design rate helps maintain flow better than some older models, though we can't guarantee exact pressrue drop without your system specs.

Water Filter in Use

It works well for homes or small cafes with municipal supply, just don't expect it to handle well water without a pre-sediment filter first — that's a real limitation but worth knowing upfront.

Filter Cartridge Options

Anyway, the HS code is 8421211000 for customs, and you'll want to confirm the port size when you order.

Frequently Asked Questions

What port sizes are available for the NW-PR303, and do I need to specify when ordering?

The NW-PR303 comes in 1/2", 3/4", and 1" port sizes. You'll need to let us know which one you need when placing your order so we ship the right version.

Does this unit come with a wrench and bracket included?

Yes, it includes a steel bracket and a wrench right in the box, so you can mount it and tighten connections without buying extra tools.

What's the minimum order quantity for this pre-filtration unit?

Our MOQ for the NW-PR303 is typically 50 units, but for smaller trial orders we can sometimes work with 20–30 pieces depending on stock.

Is the water from this filter safe to drink directly?

No, it's a pre-filtration unit, not for straight drinking. It's designed to remove larger sediments and protect your main water system—still needs a finer filter for drinking.

What certifications does this unit have, and can you provide the documents?

It's CE and RoHS certified, so it meets EU safety and material standards. We can send you the certificates and test reports upon request.
