In the 12th position is the Filtrete Maximum 3US-MAX-S01 model which is the most economical pick on this list and one of the few wonderful water filters on the market that’s priced $100.
- The Best Under Sink Water Filter – Our Pick
- 15 Best RO Systems
- 6 Best Whole House Water Filter Systems
The unit is part of three models under Filtrete’s 3US series with the other two being the Standard (3US-AS01) and Advanced (3US-PF01) water filters.
The major difference between these three models is their filtration capacity but the Filtrete 3US-MAX-S01 which we are going to look at below stands out in terms of getting rid of contaminants as it provides the highest rate of filtration. It’s cheaper and definitely more dependable than the other two models.
The Filtrete Maximum 3US-MAX-S01 is a simple 1-stage system featuring a high capacity filter media that has received both the NSF 42 and the much stringent NSF 53 certifications. This means it’s very capable of significantly enhancing the quality of your municipal water.
The system utilizes a 0.5-micron carbon block filtration medium which is way effective compared to basic carbon-based filters with the ability to remove 97% of chlorine taste and odor alongside other select chemicals like the pesticide toxaphene, herbicide atrazine, and select pharmaceuticals.
It has the additional capability of clearing out lead and microbial cysts (giardia and cryptosporidium) by over 90%. The filter is also able to trap sand, dirt, rust and other particulates present in your water down to 0.5 microns which is a huge plus because a lot of other carbon filters can only reduce particles that are as small as 5 microns.
The fact that it meets the NSF 53 certification means that it’s relatively sufficient to remove VOCs and other heavy metals although not to a large extent.
From our own assessment, we would say that this is a system that’s more geared towards dealing with heavily chlorinated water and lead, and several common city water issues as well. It’s not a unit for use with well water.
Capacity and Efficiency
We mentioned earlier that filtration capacity is the major factor that differentiates the three models in Filtrete’s 3US series. Both Standard (3US-AS01) and Advanced (3US-PF01) water filters provide a maximum of 2,000 gallons filtration capacity.
As for this Filtrete Maximum 3US-MAX-S01 model, it’s rated to process up to 1,500 gallons of water before it requires to be changed.
It’s a little lower than its counterparts but still, it’s on the higher end when you put it side to side with the other contenders herein. Even so, Filtrete recommends a 6 months replacement cycle which makes it no different to the other picks with lower capacity.
Apart from the large capacity, this unit will deliver water at a rate of around 1.5 gallons per minute. That’s faster than what many competing sing-filter systems can offer. It’s more than adequate to cater for the needs of those with regular high water usage.
Installation and Maintenance
For installing the system, it’s an easy DIY process with only a single filter to mount inside your under sink cabinet where it will fit nicely without taking up so much space. It’s extremely compact and it works with any standard kitchen faucet, so drilling is needed.
Maintaining this system is easy too. You just have a single filter cartridge to replace which should be done twice a year.
One weak point we noted though is that the unit utilizes a simple push-in design to connect the tubing to the plumbing instead of a secure compression fitting.
Therefore, the connections may possibly not be that secure and can lead to leaks in case of very high pressure. The fittings plus the faucet are made from plastic hence are also not as sturdier as the other picks that use metal.
All in all, being a low-cost under sink water filter that pretty much does its job well, the Filtrete Maximum 3US-MAX-S01 is definitely a convenient option for those that don’t want to break the bank. It will save you money and provide the necessary filtration performance to keep your tap water clean and safe.
