A: They are premium prefilters and same as oem quality. You can buy with confidence.

A: 4870 isn't listed with compatible models so I would think not.

### ⭐⭐⭐⭐⭐ quality filters
*by M***R on September 22, 2025*

Good fit, works the it should, quality material. The price was very good. needs changing as directed. No odors and cleans up allergens. the noise is like background noise for sleep.

### ⭐⭐⭐⭐⭐ Good Fit and Effective Filtration
*by D***R on September 5, 2025*

These replacement filters fit my Guardian purifier without any trouble. Installation was simple, and the filters sat snugly with no gaps or loose edges.The HEPA part does a solid job catching dust and allergens, while the carbon pre-filters help with everyday odors from cooking and pets. After swapping them in, I noticed the air smelled fresher within a day.The quality feels sturdy, and with two in the pack, it’s convenient to have a spare on hand for the next change. They make maintaining the purifier easy and reliable.
