If you’re looking for a new filter, Aquasana is a leading brand in the industry.

Price Range: $

The Aquasana AQ-4000 is a countertop water filter unit that sits next to your kitchen sink. It’s very simple to install, even without any plumbing knowledge. The unit features a simple switch that, when activated, diverts water from your faucet into the separate filter, which is filtered and flows back to the faucet for pouring.

The advantages to a unit like this are affordability and ease of use. There’s no complicated installation needed, so anyone can set this unit up. Some Aquasana water filter reviews did mention that replacing filters on this unit requires a bit of patience, but you should only have to do that every 6 months or so.

Based on the filter life, the long-term costs of this unit are 11 cents per filtered gallon, which is far more affordable than many options. Click here to learn more!

Where to Buy Aquasana Water Filters

Aquasana products are available direct from the manufacturer, on third-party websites like Amazon, and at select local stores.

For best results, we recommend buying direct from Aquasana. You can follow this link to browse their products directly from the manufacturer’s website.

Buying direct has a number of advantages, such as:

  • Guaranteed authentic products, as you’re buying from the manufacturer
  • Guaranteed latest model (some third-party sellers have older units for sale on Amazon/eBay/etc)
  • Typically the best pricing available (particularly with our discount code AQWFD50)
  • Automatic warranty registration and easier claims process
  • Better customer support

With all that said, we understand the desire to shop at a familiar retailer like Amazon. Amazon has many Aquasana products listed. If you choose to go the Amazon route, ideally you should try to buy from a reputable seller, such as Amazon.com or Aquasana itself (via Amazon). We also recommend doing a price comparison between Amazon and Aquasana direct.

Aquasana Product Warranty Information

Aquasana Warranty info
Aquasana offers a limited warranty on most of their products. If you purchase direct from Aquasana, your product will already be enrolled in warranty coverage. If you purchase from a third-party retailer like Amazon, you must register your product here on Aquasana’s website. After you purchase an Aquasana product, you should go ahead and register it right away so you don’t forget.

Aquasana generally offers very good warranty coverage, but it’s important to know that warranties vary depending on the product you purchase.

For instance, whole-house filters like the Rhino typically come with a 6-year limited warranty, detailed here. On the other hand, smaller systems typically only come with a 2-year warranty (details here).

The terms of these warranties also vary, so read the fine print on your individual product. That said, generally speaking these warranties:

  • Cover manufacturer defects and faults that prevent the unit from proper functioning
  • Do not cover accidental damage, or damage caused to your home by a product failure
  • Contain exclusions of coverage if you use third-party parts/filters
  • May or may not charge shipping & handling fees for warranty claims

So basically, if your Aquasana product is not working properly due to a fault caused by a manufacturer defect, then Aquasana will repair or replace your unit if it’s under warranty. But if something else causes damage to your unit, such as a mistake during the installation process, it will likely not be covered.
