Where to get a filter lens for a EF-S 18-55mm f/3.5-5.6 lll

Hi, I’m new to photography and I’m wondering which filter I should buy and where from? I have looked on canon’s website but I noticed that they are expensive, so I was wondering if anyone had a more budget friendly option while still being good quality?

UV Filters were only useful for film cameras.  All modern cameras (to include those at least 10 years old now) do not need a UV filter as a filter exists over the sensor.

Unless one obtains a UV filter that would block wavelengths above around 409 to 422 nm, the one over the sensor would be doing all the work.   Virtually all UV filters only block wavelengths to up to around 395 nm; with some only blocking to up to 330 nm.  Refer to a fairly recent article entitled "Why UV Filters are Basically Useless on Modern Cameras" at petapixel dot com for a ton of details.

There are many other articles as well.  It's something I had researched when picking up my first DSLR in 2013.  At that time, I went forward with clear filters.

Edit: fixed terminology - I had incorrect stated "frequency".  Updated to be "wavelength".

"For an inexpensive, easily replaceable lens like the 18-55 I would not worry about it."

This is the best advice.

Further, other types of filters with a very few exceptions have become obsolete with todays editors. Save your money to buy some more lenses.

The lens is inexpensive and easily replaceable which is indisputable.  But a filter is is even less expensive and more easily replaceable.  For those of us that are paranoid, overly cautious or otherwise have drank the koolaid, we would not think of leaving the house if our lenses didn't have UV filters and hoods on them. 

I guess a "worst case scenario" would to be out shooting somewhere and somehow damage the filterless front element of a lens and therfore be out of commission until the lens could be replaced.  However if the a filter was on the front of the lens, the filter may be trashed but could be unscrewed, discarded and you'd be back in shooting pictures in a minute.

Back in the day when lenses were purchased over the counter at a camera store from an actual camera salesperson, you could count on that salesperson asking after closing the sale for a lens asking "do you want a skylight or UV filter for the lens" and watching their eyes light up when you said "yes" or getting the lens doomsday speech if you refused. It was more or less automatic, like being asked at the drive thru "Do you want fries with that?"

You like to spend other peoples' money, huh?  An $8.99 filter is not worth the investment to protect even an 18-55?

"An $8.99 filter is not worth the investment to protect even an 18-55?"

An $8.99 filter isn't worth $8.99!

"There are filters that say "UV/Protective filter" for that reason."

Simply a hold over from the golden olden film days.  You need to update to the digital world.

I'm quite up to date, thank you very much.
