1. Define the buyer’s decision
Before comparing brands, we identify the actual decision: product type, available space, installation needs, budget, expected use, and the conditions under which ownership becomes inconvenient or expensive.
2. Record verifiable specifications
We collect price, dimensions, electrical and plumbing requirements, warranty language, return terms, recurring supplies, maintenance, and customer-support channels. Prices and policies can change, so material facts are date-stamped.
3. Label claims by source
A statement from a manufacturer is described as a manufacturer claim. Regulatory status, study findings, and safety statements are checked against appropriate primary sources whenever practical. Unknown or conflicting information is labeled rather than guessed.
4. Compare ownership—not just features
Our comparisons include setup, cleaning, energy use, consumables, return shipping, restocking fees, warranty exclusions, service access, and the likely total cost of ownership.
5. Protect editorial independence
Affiliate availability is a commercial consideration, not a quality score. A brand cannot purchase a ranking or approve our conclusion. Sponsored placements, if ever accepted, will be separated and labeled.
Corrections
If a manufacturer or reader identifies a factual error, we review the primary evidence and correct verified mistakes. Material corrections will include a visible update note.
