Okay, I need to tackle the user's query about whether air purifiers help with dust and explain how they work. Let's start by breaking down the main points. The user wants a detailed explanation but in simple terms. They also emphasized avoiding AI detection, so the content needs to be original and not formulaic.

First, the headline. It should be SEO-friendly. Maybe something like "Can Air Purifiers Reduce Dust? How They Work and What You Need to Know." That's clear and targets the key question.

Now, explaining how air purifiers work. I should mention different types of filters, especially HEPA since it's crucial for dust. But also touch on other technologies like activated carbon or ionizers, though those might not be as effective for dust. Need to clarify that HEPA is the main player here.

The user wants technical terms explained. So when I mention HEPA, I'll define it as High-Efficiency Particulate Air filter. Also, explain microns for particle size. Maybe compare dust mite size to human hair to give a tangible example.

Pros and cons are required. Pros would be trapping allergens, reducing buildup, helping with allergies. Cons could be maintenance costs, noise, and not eliminating all dust sources. Need to present these in a balanced way.

The FAQ section needs 4-5 questions. Common ones might be how often to replace filters, if air purifiers help with allergies, differences between HEPA and other types, and placement tips. Make sure answers are concise but informative.

Avoid marketing buzzwords. Instead of "whisper-quiet," say "some models can be noisy." Keep the tone conversational. Use contractions like "don't" and "you'll." Vary sentence structure—mix short and long sentences. Maybe start with a personal touch, like mentioning dusty rooms, to make it relatable.

Need to add subjective experience where possible. For example, mention that while air purifiers help, they aren't a magic solution—you still need to clean regularly. That adds nuance.

Check for burstiness and perplexity. Use active voice. Instead of "Dust is captured by the filter," say "The filter captures dust." Transition smoothly between sections with phrases like "Here's the thing" or "On the flip side."

Make sure to explain why HEPA is effective—because of the dense mesh trapping particles. Compare to a spider web analogy. Also, note that while purifiers reduce airborne dust, they don't handle settled dust, so vacuuming is still necessary.

In the FAQ, address whether all air purifiers are the same. Emphasize HEPA's importance. Clarify placement near problem areas but not blocked.

Finally, ensure the MDX format is correct, using components for ProsCons and Faq. No markdown, just direct content. Double-check for any repetitive phrases or structures to keep it natural.
