How we pick

A reader should be able to reproduce any number on this site from this page. That is the standard, and it is the thing the competition cannot copy without doing the work.

What we do not do

We do not test these products. We own none of them, we were sent none of them, we run no lab, and we have no premises. Nobody here holds a credential of any kind - not a certification, not a license, not a qualification relevant to wax, fragrance, electrical safety or veterinary medicine.

We have accepted no press samples, no free product, and no sponsorship. No brand has paid for placement and no brand has seen a page before it went live.

Every page ranking above us for the terms we care about leads with a testing claim: a 45-day protocol, "tested countless wax melts over the years", "expert reviews". We cannot honestly imitate that and we are not going to try. What follows is what we do instead, and it is checkable in a way "we tested it for 45 days" is not.

What we do instead

  1. Compile published manufacturer specifications. Rated wattage, bulb fitment, dish diameter, cord length, timer behavior, dimensions, capacity; for melts, wax type, pack weight, count and stated hours. Every figure carries the source and the date we read it.
  2. Read the manufacturer's own pages and documentation in preference to a retailer listing. Where no manufacturer documentation exists - which in this category is most of the time - we use the retailer listing and label it as a retailer listing rather than dressing it up.
  3. Compute the electrical load and running cost from the rated wattage, with the formula printed and the electricity rate labeled as an assumption.
  4. Check every safety claim against a named authority - the NFPA, Pet Poison Helpline and VCA Animal Hospitals - cited by name in the sentence and linked at the point of the claim, never in a footer.
  5. Report where a figure does not exist. A field with no published value prints "Not published". We never fill a gap with a plausible number from a similar product.

A note about this category specifically

Wax melts and warmers are unusually badly documented, and it shaped this site more than any other single fact.

Most warmer hardware on the US market is sold by brands with no manufacturer website and no downloadable manual. Of the ten warmers we index, four publish a rated wattage - and three of those four are from one maker. Not one of the five candle warmer lamps publishes a wattage, which means nobody can tell you what any of them costs to run.

On the consumable side it is no better. Three of the five melt brands we index publish no hours figure at all, and hours is the denominator of every value comparison anyone would want to make.

So we rank heavily on documentation. That is not a preference for tidy paperwork - it is that a product whose maker publishes nothing cannot be compared with anything by anybody, including you.

What we rank on

Warmers

  1. Is a rated wattage published? It decides running cost and is a rough proxy for throw.
  2. Is the consumable named? A warmer whose bulb has a real designation is one you can still run in three years.
  3. Is the timer behavior specified? Not "has a timer" - what it does when the time runs out.
  4. Is the dish usable and easy to empty? Silicone beats fixed ceramic, and this is where the difference in daily use actually sits.
  5. Are dimensions and capacity published? Decides whether it fits your shelf and your jar.

Wax melts

  1. Is an hours figure published? Without it, value cannot be computed.
  2. Is the wax type published? Decides melt temperature and throw character, and matters to anyone avoiding paraffin.
  3. Is weight per cube stated or derivable? Six cubes tells you nothing; ounces do.
  4. Does the fragrance do a specific job? Odor elimination is a different product from fragrance.

What we do not rank on: appearance, star ratings, review counts, or how a listing photographs.

Our assumptions, listed

An assumption is not a fact and this site labels them wherever they are used. These are all of them.

Assumptions used in calculations across this site

Electricity rate17 cents per kilowatt-hourUS residential rates vary by more than a factor of three between states. Every formula is written so you can substitute your own.Annually
Daily running hours6 hoursA long evening, every day - more than most people actually run a warmer, so cost figures are conservative.With each refresh

Per-cube weightsPack weight divided by countOur arithmetic from published figures, not a separate manufacturer claim.With each refresh
Where a calculation uses one of these, the page says so next to the number rather than burying it here.

Prices, and why one is sometimes missing

Prices render from a live data layer only. A refresh job re-reads them and stamps the file with the time it ran; anything older than 48 hours is treated as stale and simply disappears, and the buy button falls back to "Check price on Amazon".

That is deliberate. A stale price on a review page is worse than no price - it is a number that looks authoritative and is wrong. So a missing price on this site is the system working, not a bug.

We also do not publish star ratings or review counts of our own, and we emit no rating in our structured data. We run no tests, so we have no rating to give. Where a third-party rating appears it will be pulled live and attributed to the retailer - never typed in by hand.

What would change our mind

A pick moves if any of these happens:

  • A maker publishes a figure we said was missing. Several products are ranked below where they might otherwise sit purely because of an unpublished wattage or hours figure. Publish it and they move.
  • A published specification turns out to be wrong - a wattage that does not match the plate on the unit, a capacity that does not hold what it says.
  • A cited authority updates its guidance. The safety pages are rechecked every six months and immediately on any update from the NFPA, Pet Poison Helpline or VCA.
  • A product stops being available, or a buy path we linked stops being valid.
  • A reader shows us we are wrong. This has the same weight as the others.

What will not change a pick: a higher commission rate. Where a product we rank highly has no verified buy path, we say so and link nothing rather than sending you somewhere we have not checked. How this site is funded.

How to correct us

Email info@thewaxindex.com or use the contact form. If you can point at the source, so much the better - but you do not need to.

Corrections are dated and logged rather than silently edited, and every page carries a "sources last checked" date that reflects real verification rather than an automatic stamp. The full policy is on the editorial policy page.

If something on this site is wrong we would rather hear it from you than leave it up.
