Frequently Asked Questions

1. How do I choose the right air purifier for my room size?

It starts with CADR rating and room coverage. I’ll break down the math – plus factors like filter types (HEPA vs. activated carbon) – based on rooms from 10㎡ to 50㎡.

3. What’s the difference between 1080p and 4K projectors for home use?

Resolution matters, but so does your space. I’ll share when 4K is worth the splurge (hint: large screens) and when 1080p still shines for small rooms or casual viewing.

2. How often should I replace air purifier filters?

It depends on usage and air quality. I’ll share signs your filter is due (like reduced airflow) and budget-friendly tips for maintenance.

4. Can a projector work well in a bright room?

Lumens and screen type are key. I’ve tested projectors in sunny living rooms – here’s what works (and what doesn’t) to avoid washed-out images.
