Preface! ✨

Hello everyone!

My intentions for writing these articles are:

  • Explain technical information about aerogels in simple terms (to the public)
  • Store information and habits for my future self and others (in <7 minutes)

Coolio? Sweet. Enjoy the series :-)

TL;DR Water Purifiers In Developed Countries 🚰

There’s a pushback in the research.

We were focused on how people would approach the filter… Until we were asked:

“How do big cities or small villages in developed countries filter their water? Is it a personal filter, or is it a large filtration plant? Perhaps the solution is already been made, just reapply it under the conditions of where you wanna start.”

This led me down a rabbit hole of exploring how the communities in the US filter their water… compared to small villages in Mexico.

The National Science Foundation put together a list of water filtration companies based in the US.

The list can be found here.

Three companies that were analyzed for water purification personalization are as follows:

  • AOS Smith
  • Amway Filters
  • Ahlstrom Filters

AOS Smith water purifiers contain a two-stage drinking water replacement.

This filter can attach itself to the sink under the bathroom.

This purifier is a filter cartridge… aka residential filter.

Residential water filters are applicable for both point-of-entry and point-of-use devices, including whole-house filters, countertops, tap, pitchers, appliances, etc.

They remain in the household.

Amway Filters make personalized filters (containers & cartridges).

These filters can be attached directly via the kitchen sink or indirectly as a water pitcher (Brita Filter).

An advantage is that a signal notifies the owner when the water is unsafe for potable applications.

The primary signal is a red light followed by a beeping sound.

This filter is also a residential filter… it stays in the house.

Ahlstrom Filters has quality examples of personal & residential water filters.

Personal water filters are highly adaptable to small personal hydration devices such as water bottles and backpacks.

Examples Include:

Ahlstrom’s water filters can attach to a water bottle, container, or tube. The feature is in their adaptability.

Final Conclusions 💭

Many water filters are residential…

It includes filters like Ahlstrom, AOS Smith, etc.

But other filters are made for walking to water sources and drinking it there…

It could be a river, lake, pond, or public water tap (source)

Some examples include LifeStraw, Sawyer, & Aqus.

These filters target people who walk to find water.

The target customers confront a similar situation to the description of personal water filters:

They must walk to find their resources.

Let’s continue building personal water purification. 🚶
