This clip covers a Sport Berkey Portable Water Purifier that is considered as a vital equipment of emergency preparedness. It is small-sized, with an effective 50-year supply life, and able to treat contaminants from different water sources, allowing it to be convenient in emergency situations.

Aquasana AQ-4100 - Unboxing and Setup

The video features the unboxing and setup of the Aquasana AQ-4100 shower filter system, highlighting installation challenges, initial debris discharge, and the benefit of softer, cleaner water.

My skin feels good, the shower doesn't smell like chemicals, my highlighted hair looks like I had it done yesterday instead of two months ago. This was fairly easy to install for someone who's 5'4" with a shower head that's about a foot above my reach. Thankfully my ladder fit into my bathtub! That's nothing to do with the product. The instructions were pretty easy to follow, tool use minimum. Just screw off the old shower head, use some plumber's tape, use the gaskets provided, screw on the new Aquasana device, flush out the charcoal, and you're good. Well worth the price to shower with clean water and have a handheld shower wand with multiple settings so you can pick and choose your water experience. I recommend to people they install one.

Buying Guide: How to Choose the Water Filter That’s Best for You


The type of water filter system you choose should depend on what you need it for. Different systems are better suited for different purposes.

Exploring Different Types of Water Filters and How They Remove Contaminants

Discussing water filters is similar to discussing cars; there are many different types, each with its own pros and cons. You’ve got filter pitchers, portable or gravity water filters, whole-house filtration systems, under-sink and countertop units, filtered water bottles, shower filters, faucet filters, and of course, reverse osmosis systems. Each type serves a unique purpose and fits different needs.


Talking about water filters can be made analogous to cars; there are various varieties, all with their own pros and cons. There are filter pitchers, portable or gravity water filters, whole -house filtration systems, under-sink and countertop units, filtered water bottles, shower filters and faucet filters, and let’s not forget reverse osmosis systems. Each one has its own specific mission and goal and can be utilized in different environments.

Likewise, the specific water filtration process or media used by a unit can vary. For example, one countertop filter might use an ultrafiltration membrane to tackle heavy metals and solids, while another combines activated carbon with UV light treatment to remove chemicals and bacteria.


Bottom line: Take some time to explore the different types of water filters available. Or, if you’re in a hurry, check out our list of favorite products above. We’re confident you’ll find something that catches your eye.

You’ll quickly realise that there are varying water filtration process or media employed by a various units on the market. For instance, one unit may use an ultrafiltration membrane to address heavy metals and solids and another unit combines activated carbon with UV light treatment to remove chemicals and bacteria.


Bottom line: Dedicate some time for yourself to explore the different water filters on the market. Alternatively, if you don’t have much time, you can browse our list of finest products in the section above. We are sure that you’ll select something which you really like.


Understanding NSF Certifications

Water Filter Manufacturers often make a point of showing of their certifications and badges. NSF testing and certifications by independent laboratories guarantee that a certain model does indeed perform as advertised. Lets take a look of what these certifications mean:

  • NSF standard 42 tests for chlorine reduction and water aesthetics.
  • Standard 53 was established for contaminants with health effects – think heavy metals.
  • Standard 58 is for RO systems specifically.
  • NSF standard 244 covers testing for the reduction of bacteria and viruses.
  • Standard 401 looks at so-called “emerging compounds“ not yet regulated by the EPA.
  • And lastly, protocol P473 is for PFAS which you’ve might already heard of (not to be joked about).

The Big deal with Installation and Maintenance

Depending on which filtration technology you choose, you’ll get a larger or smaller filtration capacity, pure water flow rate, and storage capacity.

Pro tip: If you don’t like to wait for clean water being produced when you’re thirsty, make sure that a system can meet your daily demand even at times of peak consumption before you spend any money.

What to consider on Filtration Capacity, Flow Rate & Water Storage

Cost and required work for installing and maintaining a water filter highly depend on what type it is. Simply put, a POE water filter is more difficult to set up than a pitcher.


We made sure to include information regarding installation and maintenance for each product reviewed on top.

Life Time Costs

It’s pretty obvious: Larger and more complex water filtration systems are more expensive.


That said, you should not only take into account the initial cost for purchase and installation but also for maintenance, meaning replacement filter cost. Standard-sized filter cartridges allow you to switch to off-brand replacements to save.

What Is a Water Filter?

A water filter is any device designed for removing impurities in water using a biological, chemical, and/or physical process. Thereby, in residential applications most water is filtered for drinking purposes.


The most common water filter types include pitchers, whole-home systems, under sink filters, countertop systems, and faucet-mounted units.


By the way, filtration is just one method used to treat water with the goal of purifying it. There also are distillation, sedimentation, chlorination, ultraviolet light radiation, and flocculation.

The Different Types of Water Filtration Systems

Like we said, there’s more than one type of water filter. Each works a little different and therefore has its own benefits…

Pitcher Filters

Pitcher water filters rely on gravity to pump the water via the filter to the clean discharge. They are neat, mobile and carried around.They don’t require installation. Another advantage of public transportation is that is it really cheap. Absolutely not surprising to them that they became the widely used type of water filter!

Gravity Filters

Corresponding with pitchers, this filter type is also and equally based on gravity principle that makes water flow through at least one filter component. Usually the filtration procedure is really a very fine one however you will get the best quality water for your drinking as a result.

Portable Filtering (Straws, Pumps, Gravity Bags…)

When we’re talking about portable water filters we usually mean those designed for outdoor use: Backpacking, hiking, camping, or traveling. Preppers also like portable systems to be prepared in case of emergency. They don't just provide cosmetic benefits but they provide drinking water free from bacteria, protozoa, and viruses.

Whole House Filters

Also called point-of-entry systems, these water filters supply your entire home. Bathroom taps, showers, kitchen faucet, home appliances – you’ll have purified water at every outlet.
You will most commonly find catalytic or activated carbon filters.

Under Sink Systems

They get installed under your kitchen sink and provide filtered drinking water at a single outlet. Most are effective at removing a wide range of harmful contaminants, while still being affordable. Easy installation, simple maintenance, and convenient use are why people love under sink filter systems.

They are placed under your kitchen sink and there you have a water filter for all your drinking water needs one spot. Generally, these filters operate to remove a broad spectrum of the harmful impurities. Easy installation, simple maintenance and convenient use attract many customers towards these filter systems.

Countertop Water Filtration Systems

A typical sink or countertop filter will provide ant access to clear water simply by removing the desired filter cartridge and installing it without any expensive additional installation. With just a quick, one-time set up to any regular screwed-in faucet, this filter will be ready to use in less than 5 minutes. More benefits: Compact and mobile. You can carry it anywhere, even around our neighborhood. In addition, the cost is affordable.

Filter Bottle

A water purifier with bottle is going to be perfect if you desires smart drinking water while you are on move.

Shower Filters

It can be a very good choice for you if you tend to have allergy reactions to chlorine.The latest models can achieve even higher levels of contamination removal that will benefit your skin, hair and nails.

Faucet Mount Filters

Faucet units easily connect to any standard faucet or tap. No need to make permanent changes to your plumbing system. Required budget? Surprisingly small.

Reverse Osmosis Systems

Last in our list however not the least is the reverse osmosis systems. These include countertop and under the sink varieties, as well as whole-home systems that employ multiple filtration steps. The very basis of each system is an RO membrane with the capacity of rejecting up to 99% of water impurities.

Our Favorite Water Filter & Purifier Brands

SimPure & AquaTru

Personally, we find the SimPure and AquaTru to be the leading reverse osmosis systems. they are NSF-certified to remove the most contaminants of all models on the market.


Berkey is the most popular brand when it comes to gravity water filters.


Clearly Filtered provides the best water filters in the under sink system, bottle, inline, and pitcher category.


If you want a POE water filtration system or water softener for hard water, we recommend you go with SpringWell. They are super high-quality and come with excellent customer support and lifetime product warranty.


Brita is a great option if you want a filter that improves water aesthetics. However, we usually don’t recommend Brita for more serious contaminant removal.

Should You Get a Water Filter? Here's What to Consider

This is the most important question which one needs to answer while thinking to install water filter in their house. It depends on whether , how many,and which contaminants are present in the local water source. Bearing it in mind, a water filtration method is not simply about foul taste and odor – that is so unduly far from the truth. It will be established that the deadliest water contaminants are undetected by our senses. Lead, which is known to be a neurotoxin and undetectable by the naked eye, the senses of taste and smell, is among the most prominent.

Tips for Checking Your Water Quality

And so, what should you do to find out whether the water at your home is safe to drink?Through testing! Alternatively, if you can’t stand the thought of spending any money on this or you’d rather not, you can always check out the free water quality report from your local waterworks using this website here – EWG Tap Water Database – or this one – EPA CCR reports or this one if you are not on a small or private system.
