Once you know the exact filter or part, where you buy still matters for price, shipping speed, and counterfeit risk.

| Home Depot | OEM appliance parts, pickup | Higher on some aftermarket |
| Lowe's | OEM brands, pickup | Fewer compatible options |
How to avoid counterfeit filters
- Prefer sold by the brand or a known authorized seller.
- Look for NSF marks (what they mean).
- Read recent reviews about fit and taste.
- Be skeptical of prices far below the market.
OEM vs. compatible — where each wins
- OEM: Home Depot, Lowe’s, and Amazon usually stock them.

FAQ
Is Amazon safe for water filters?
Yes if you check the seller and reviews. Prefer Amazon.com or the brand store when possible.
Should I buy the cheapest listing?
Not if it lacks NSF marks, model fit notes, or has repeated “doesn’t fit” reviews.
Do you sell filters directly?
No — Filter Searcher is a lookup tool that links out to retailers.
