## Heuristic (14)

- A higher CADR (Clean Air Delivery Rate) means faster purification for your space. · measured
- True HEPA or medical-grade H13 filters capture 99.97% of fine airborne particles like dust, pollen, and smoke. · measured
- To clean a dryer vent, you should follow a step-by-step process using a vacuum and a flexible brush kit. · assumption
- Before cleaning an electric dryer, you must unplug it, or turn off the gas valve if you have a gas dryer. · assumption
- When scrubbing a dryer duct with a flexible rod and brush head attached to a cordless drill, you should run the drill in a clockwise direction only, slowly moving it forward and backward. · assumption

## Convention (0)

- none

## Expectation (0)

- none

## Pitfall (7)

- You should never use high heat sources, hair dryers, or compressed air to dry a K&N air filter, as heat can shrink or damage the cotton media. · assumption
- Using the wrong chemical, such as brake or carburetor cleaner, can permanently damage the fragile sensing elements of a Mass Air Flow (MAF) sensor. · assumption
- You should never let the plastic straw or your fingers physically touch the delicate sensor wires of a MAF sensor. · assumption
- You should never use compressed air to speed up the drying process of a MAF sensor, as it can snap the delicate wires. · assumption
- Corrosive chemical drain openers like Drano should never be used to clean AC drain lines, as they will ruin HVAC pipes and equipment. · assumption

## Trade-off (2)

- Third-party filters are cheaper but may have a shorter lifespan or leak particles. · measured
- HEPA air purifiers are highly effective at removing fine particles but require filter replacements, whereas water-based purifiers are lower maintenance but less effective at filtering micropollutants and need daily cleaning to prevent bacteria. · measured

## Benchmark (1)

- The Coway Airmega Mighty2 is priced around $270 and offers fast particle removal, quiet operation, and an advanced laser sensor with real-time air quality readouts. · measured

## Stance (0)

- none

## Limits

- This ontology does not cover air purification systems for automotive use (e.g., car cabin filters, engine air filters).
- It does not include general HVAC system cleaning products (e.g., duct cleaning, AC coil cleaner) unless they are explicitly air purifiers designed for HVAC integration.
- Specific technical details of air purification mechanisms beyond common attributes like HEPA or UV are not deeply explored.
- The ontology does not include detailed market share, sales figures, or specific revenue data.
- For 2 nodes, the model could not provide supporting search queries, so **actual collected queries** (including related searches and PAA) overlapping with labels were found by rule and attached as evidence. The evidence for these nodes is only accepted as 'derived'.
