Frizzlife MD40 Electric Water Filter Dispenser: features and specs

The Frizzlife MD40 is a countertop water filter that pumps water through its filters at the press of a button, instead of waiting for gravity as a jug-style pitcher does. It runs on a rechargeable battery, so it needs no power cord during use. Here is what its specs mean and what to confirm first.

How it works

Most filter pitchers rely on gravity to pull water through the cartridge, which can be slow. The MD40 uses a small electric pump. Frizzlife says it delivers water about five times faster than a gravity pitcher, with simple press-button operation. The model number listed is MD40-2F, and the package comes with four filters.

What the filters do

Frizzlife describes a dual-filter "CBX" design that reduces chlorine, lead, fluoride and PFAS, and says it removes 99.89% of the contaminants it targets. The listing shows NSF/ANSI 53, 42 and 372. Check the certification paperwork for exactly which claims each standard covers.

The brand also says the system keeps natural minerals such as calcium and magnesium. As a result, it does not lower TDS (total dissolved solids), and Frizzlife notes that TDS is not a professional measure of water quality. A TDS meter will therefore read about the same before and after filtering. That is expected for this type of filter and does not mean it is faulty.

Filter life and reminders

Each filter is rated for up to six months or 400 gallons, which Frizzlife describes as twice as long as standard options. The unit monitors usage and gives a reminder when a replacement is due. Real filter life typically depends on your water quality and how much you use, so the reminder is a better guide than the calendar.

Battery and portability

The built-in 4500mAh battery is rated at about a month of cord-free use per charge, and it charges like a phone. This makes it easy to move around, and Frizzlife suggests RVs, camping and power outages. It is a compact unit at 5.0 x 5.0 x 13.5 inches (about 13 x 13 x 34 cm) and 5.1 lb (2.3 kg).

One quirk is worth knowing. If the battery runs completely flat, the MD40 will not restart on its own after charging. Press both blue filter buttons together for three seconds to restart it.

Who it suits

It suits renters, small households and offices that want filtered water without any plumbing work. It also suits people who find pitchers slow to refill and want a unit they can carry between rooms or take to a campsite.

What to check before you buy

• Your water source: the MD40 filters water you pour in, so you will refill it by hand. Check the reservoir size in the manual.
• What you want reduced: read the certified claims to confirm they cover your concern.
• TDS expectations: it keeps minerals, so it is not designed to lower a TDS reading.
• Space: allow for the 13.5-inch height under shelves and cabinets.
• Charging: you need a suitable charging setup and a habit of recharging before it runs flat.
• Upkeep: check replacement filter availability and how to clean the unit.

The short version

• A rechargeable countertop dispenser that pumps water through its filters at the press of a button.
• Filters are rated up to six months or 400 gallons, with a replacement reminder.
• 4500mAh battery, about a month of cordless use per charge, per Frizzlife.
• NSF/ANSI 53, 42 and 372 listed; keeps minerals, so TDS readings don't fall.
• Restart a fully drained unit by pressing both blue buttons for three seconds.
