Aquasana AQ-4000 Review (2022)
The importance of drinking water and the difference it makes to your health is a no-brainer. However, if you’re choosing water over a cuppa Joe, you’ll want to ensure your expectations are met. While tap water ushers in immense convenience and should be the obvious choice, it’s not always as pure as you might assume.
Given that you typically don’t need to sterilize your water before consumption, it’s easy to assume that there are no qualms with what stems from the faucet. While the chances of being instantly struck down with a case of diarrhea are slim, swigging the water that comes out of your faucet can still cause adverse repercussions.
Here’s where a countertop water filter comes into play. However, finding the best unit can be an uphill battle with the wealth of options that have littered the market. In this Aquasana AQ-4000 review, we’ll explore why it’s one of the best options to consider.
Aquasana AQ-4000 Review: Features
Like other high-end products, the Aquasana AQ-4000 contains amazing features that make it a worthwhile investment for household use.
1. Two-Stage Claryum Filtration
The main task of a water filter is filtration. The unit uses state-of-the-art Claryum technology that entails two filtration stages to guarantee clean, pure water. The stages are further broken down into four segments.
- The activated carbon filter diminishes organic chemicals such as herbicides and pesticides from the water.
- Catalytic carbon filtration aids in the elimination of up to 97% of chlorine and chloramine. These are responsible for unpleasant odor and taste in the drinking water.
- The ion exchange technology guarantees the elimination of lead, mercury, and other heavy metals.
- Lastly, the sub-micron filters capture and get rid of cysts lurking in the water.
2. NSF Certification
Seventeen different products from Aquasana have NSF certification, including the AQ-4000 countertop filter. The brand maintains consistent compliance with the NSF guidelines. In turn, it’s been able to maintain this certification for years. All its filters undergo rigorous testing and have a data sheet that shows test results. According to the sheet, the AQ-4000 has a 99% success rate in eliminating most water contaminants.
The AQ-4000 features a sturdy build that’s complemented by a user-friendly design. Connecting it to the faucet and replacing the filters when need be is a walk in the park. Furthermore, the unit features an activated carbon filter geared towards removing up to 77 contaminants.
4. Filter Unit
The filter is housed in a rectangular white unit that’s designed to sit on kitchen countertops. The unit’s design varies from the generic cylindrical unit and occupies a larger surface area for width. Nonetheless, it’s compact and ideal for those with limited counter space between the wall and kitchen sink.
5. Flexible Faucet Adapter, Hose, and Diverter Valve
You’ll require attaching the AQ-4000 to the faucet of your kitchen sink via the diverter valve and hose. If you lack a standard faucet, you might require using the included adapter to directly connect your faucet to the diverter valve.
It’s the cherry on top for customers. You can have peace of mind knowing that the AQ-4000 is backed by a one-year warranty and a 90-day money-back guarantee, enhancing their confidence in the unit.
Aquasana AQ-4000 Review: Performance
When it comes to filtering performance, the AQ-4000 is undoubtedly one of the forerunners in the world of countertop water purification and filtration. The unit’s filter has been proven to eliminate 77 contaminants such as PFOs, lead, pesticides, mercury, pharmaceuticals, and herbicides, and it’s more efficient than other filters. Additionally, it can last for 11 times the capacity of the brand’s gravity-fed pitcher.
Once you attach the unit to your faucet, you’ll gain from your home’s water pressure forcing it to flow through the filter at an impressive rate of 30 gallons per hour. That implies you can drink filtered water immediately with no waiting time. If you prefer having immediate access to clean, pure drinking water, the Aquasana AQ-4000 is a no-brainer.
Aquasana AQ-4000 Review: Flow Rate
Once the filter is connected to your faucet, you won’t need to hang around to fill up a pan of water. Although the flow rate might slow down after a while, there’s no denying that it’s impressive at 30 gallons per hour. That will give you an adequate supply for cooking and drinking without any frustrating delays.
It’s also worth noting that contrary to other filtration systems that depend on reverse osmosis, the Aquasana AQ-4000 guarantees no water wastage. Every ounce of water that comes out of your faucet will be purified, filtered, and ready for consumption. Reverse osmosis systems can waste up to 3 gallons of water per purified gallon which isn’t ideal.
