Multipure Frequently Asked Questions

What is the difference from the Aquaversa MP750SB and the Aquaversa MP750SI?


The Multipure MP750SB comes with a faucet and all the hardware you need to install the filter under your sink. The MP750SI does not come with any hardware or faucet it is meant to be used in line such as coffee machines, fountains, ice-makers and various restaurant uses and more. It can also be used if you already have a faucet and hardware installed from a previous water filter and you just need the system without the hardware kit.

Other than that they are the exact same system and use the same replacement filters


How difficult is it to replace the filter for the Multipure Aquaversa MP750SB water filter?


It is fairly easy to replace the filters, you just want to make sure you have enough tubing hooked to it going from the filter and the valve on your water line so you can easily take it out from underneath the sink counter and hold it over a container to contain the water that will come out.

You then just unscrew the clamp that is holding the filter housing together and take the top housing off and unscrew the filter and then screw the new filter in by hand. Then just put the bottom and top canister together and clamp it back down.


Does the MP750SB Aqauversa come with everything to hook it up?

Yes it comes with everything you need to install and use. You will need to drill a 1/2" hole in your countertop or sink to install the faucet if you do not have a hole already. It also comes with a valve that hooks up to your cold water line.


After installing my Aquaversa Mp750SB I have Lots of air bubbles. Is this normal?

You might get air bubbles for the first couple days of use while the air escapes from the system. If you run it for 20 minutes or so this will help, you can also tilt the filter housing to help the air escape while the water is running through the filter. You might have to turn the adapta valve down a little also.

Is there a Warranty/Guarantee?

Multipure demonstrates confidence in its Drinking Water Systems by providing a 90 day money-back guarantee. In addition, all Drinking Water System housings have a lifetime warranty, and all system accessories are warranted for 12 months.

Can the Multipure Drinking Water System be connected to an automatic ice-maker?

Yes. Multipure below counter Drinking Water Systems can be connected to any type of water dispenser or ice maker.

If the unit does not remove minerals, how does it take out lead?

Multipure's Solid Carbon Block Filter allows certain dissolved impurities, such as lead and chemicals, to adsorb to the filter surface. Adsorption (as opposed to absorption) is defined as "the adhesion in a thin layer of molecules to the surface of solid bodies with which they are in contact" (Webster's Collegiate Dictionary). Thus, the solid carbon block is like a magnet that lead molecules adhere to.

Can hot water be run through the filter?

The biggest problem with hot water is the sloughing off of chemicals/compounds which had been adsorbed to the filter surface. Heat causes the carbon pores to open up, reducing the filtering effectiveness, and resulting in lead or chemicals being released into the water. This performance degradation occurs even though hot water is usually below 212 degrees F, and therefore not hot enough to alter the raw materials or cause damage to the filter itself. If someone does run hot water through the filter, immediately run cold water through the filter for at least 3 minutes, to cool and flush its contents. Do not drink hot water passed through the filter.
