Fair questions before you spend anything
I already have a filter on the fridge, is that not enough?
It depends what is bothering you. A refrigerator filter handles the drinking and ice water at one appliance, and it does nothing for the shower, the laundry or the bathroom taps.
If the chlorine smell in the shower is the actual complaint, a fridge filter will never fix it because the water never passes through it.
This feels like the start of an upsell into a softener.
The honest answer is that these are two different machines solving two different problems, and plenty of homes need only one of them.
If your complaint is taste and smell, a filter is the answer and a softener is not. If it is scale, the reverse is true. The test at your tap tells you which conversation you are in.
I rent, so can I even do this?
A point of entry filter is plumbed into the main line, which makes it a change to the property rather than to your belongings. That is a landlord decision, not a tenant one.
If you want something you can take with you when the lease ends, a unit at one sink is the practical option in a rental.
I do not want my shower pressure to drop.
Every filter housing costs some pressure, and a neglected cartridge costs a great deal more. That is the real risk, not the filter itself.
This is why static pressure gets measured before the housing is chosen. A house already running low pressure needs a larger housing or a different approach entirely.
How do I know the numbers on this page are real?
Every water quality figure here comes from the Las Vegas Valley Water District publications linked beside the number, and you can open them yourself.
You will notice the district publishes two hardness figures at once. The summary says 280 ppm and its FAQ page still shows an older 291 ppm. We would rather show you that than pretend the data is tidier than it is.
Can I just buy one at a big box store and put it in myself?
Plenty of people do, and the hardware is not the hard part. Sizing it to your flow rate and getting the bypass right is where self installs go wrong.
The permit question matters more than the parts. Nevada's small job exemption under $1,000 does not apply when a permit is required.
