I'm looking for a laser with an infrared filter. But I want a product that's not too expensive. Pls Which of the lasers on this list has an ir filter?
Or you can recommend another product.

As a rule of thumb, any laser that is green (532nm) and sold on eBay will generally emit IR. Other widely-available wavelengths shouldn't emit IR (unless it's an IR laser).

Thank you! How about Sanwu pocket Mint-Green 520nm, Is it bad for eye health than 492nm Cyan color?

Visible wavelength direct diode lasers do not emit IR.
Only DPSS laser such as 532nm which are not direct diode lasers leak a small amount of IR.
DPSS lasers produce that best beam quality and the round dot associated with lasers.
Direct Diode lasers generally have lower beam quality and produce a rectangular dot.

JetLasers makes high quality IR filtered 532nm DPSS hand held lasers see: https://www.jetlasers.org/index.php?id_category=38&controller=category

Output power is the key consideration in laser safety not color meaning wavelength.
It does not matter what color/wavelength any laser is. A laser with an output greater that 5mW is not eye safe.
You need laser glasses/goggles to protect your eyes while using lasers more powerful.
Powerful lasers are dangerous devices not toys and responsible safe use of them requires knowledge of laser safety.

You can get good quality Eagle Pair laser glasses/goggles here: https://www.survivallaserusa.com/Safety_Goggles/cat1667093_1527285.aspx

See Laser Hazard Chart here: https://www.lasersafetyfacts.com/resources/FAA---visible-laser-hazard-calcs-for-LSF-v02.png

Before you buy any laser read about laser safety and related on best web site covering the topic: https://www.laserpointersafety.com/

See about one LPF member who suffered permanent eye damage when 1W blue laser hit his eye for less than 1 second, here: https://laserpointerforums.com/threads/hit-in-eye-with-1000mw-445nm-blue-laser.69469/
