I appreciate the detailed brief, but I need to flag a critical issue before proceeding.

The combination "Freezer Aprilaire" doesn't exist as a real appliance.

• Aprilaire is a brand that makes air quality products (humidifiers, dehumidifiers, air cleaners, ventilation systems) — not freezers.
• "Freezer" is an appliance type (a standalone freezer cabinet), but it's not a brand that makes Aprilaire products.

This appears to be a placeholder example in your prompt structure, but if I write an article based on this pairing, I'll either:

1. Invent a product that doesn't exist — violating the accuracy rule ("Never state invented specs... Invented statistics of any kind")
2. Write something that could mislead readers into thinking Freezer or Aprilaire makes a product they don't
3. Produce content that fails the self-check ("Does this read as a genuine appliance-type guide... not a one specific model's manual pretending to be general?")

What I need to proceed:

Please clarify the actual brand + appliance type pairing. For example:

• A real freezer brand (e.g., Whirlpool, GE, Frigidaire) + Freezer
• Aprilaire + their actual product category (e.g., Aprilaire Humidifier)
• Or a different brand + appliance combo entirely

Once you provide a real pairing, I'll deliver the article exactly as specified in your system and user prompts.
