How We Choose

Why a floor plan

Household gear is easier to think about where it lives. A filter pitcher belongs to the kitchen counter, a humidifier to the room you sleep in, a shower filter to the bathroom. So the catalog on our homepage is drawn as a simple floor plan with four rooms, and every item has a room code (K1, SL2, BA1, LV1 and so on) that matches a numbered marker on the plan. Pick a room to see its group, or a marker to go straight to one item.

The room is a description of where an item usually lives, not a rule. Each entry says which room it belongs to and, honestly, which other rooms it also works in. The blog posts are tagged with the rooms they touch.

How an item earns a page

Every product entry has to pass the same checks before we write it up. If it fails one, it does not get a page.

• An established brand with a live listing on Amazon.com. We open the listing ourselves and confirm the title, the brand's store, the exact size, model or variation, and that it is in stock. We do not write about products we could only find through a search page or a reseller.
• The spec sheet, read literally. Capacity, dimensions, filter type, rated numbers, materials, noise, run time and care instructions, taken from the listing and from the manufacturer's own pages. We report what is published, and we say when a claim on the box is not backed by anything we can check.
• Standards and ratings checked at the source. A certification or rating appears in an entry only if we found it with the program that issues it. For water filters that means the certifier's own public listing, which shows the standards a product is certified to and for which contaminants. For air purifiers it means a rated Clean Air Delivery Rate published through the program that issues it. "Meets the standard", "tested to" and "HEPA-type" are not the same as certified, and we keep those distinctions.
• Public sources for the background. The explainers and the context in each entry lean on public agencies and standards bodies: the U.S. Environmental Protection Agency, the Centers for Disease Control and Prevention, the U.S. Department of Agriculture's food-safety guidance, and NSF. We describe what those sources actually say and link to them.
• A price with a date on it. Every price says when we saw it, which size or model, and which seller. A price is only true on that day. We never call a price "current", and we ask you to check the Amazon page before buying.
• A setup-and-upkeep sequence. Each entry includes a short numbered sequence for setting the item up and keeping it maintained: when to change a filter, how the maker says to clean a tank, how to check a thermometer. Maintenance is where household gear quietly lets people down, so we spell it out.

How we make money

Health News Blog earns money in exactly one way: the Amazon Associates program. As an Amazon Associate we earn from qualifying purchases. Every product button on this site goes to that product's Amazon listing, and if you buy through it we receive a small commission from Amazon at no extra cost to you.

There is no other affiliate program, no direct-seller link, no sponsored post, no paid placement, and no free product accepted in exchange for coverage. A brand cannot pay for a page here, and the commission rate on a product plays no part in whether it gets one or in what the entry says. The full version is in our Affiliate Disclosure.

What we do not do

• We do not make health claims for household gear. Air purifiers, humidifiers, water filters and kitchen tools are household products, not medical devices. We describe what an item is designed to do and what its published ratings measure; we do not claim that any of it protects you from any condition. If a listing markets a product that way, we describe the marketing neutrally and attribute it to the seller.
• We do not run lab tests. We are a small editorial team without a laboratory. When testing matters, we name the certification program and check its listing, or we say plainly that the testing status is not disclosed.
• We do not give medical advice. Nothing here is written for your situation. If you have questions about your own health, or about your home's air or water in relation to a health concern, talk to a clinician, your local health department or your water utility.
• We do not invent people. The byline on every page is Health News Blog Editorial Team. There is no fictional expert reviewing entries and no named individual endorsing anything, because we would rather you judge the sourcing than a face.
• We do not sell or ship anything. Every purchase happens on Amazon under Amazon's own terms. See Shipping and Returns.

Who writes this

Health News Blog is published by 3MAX GROUP, LLC, a company based in Lake Point, Utah. The pages are written and maintained by a small editorial team. We are not clinicians, engineers or certified inspectors, and we do not claim to be. What we bring is a process: open the listing, read the spec sheet, find the standard or the public source, date the price, write it plainly, and say when we could not confirm something.

Corrections

If something on this site is wrong, we want to fix it: a price that has moved, a rating we misread, a certification that has lapsed or never covered what we said, a standard we described too loosely, a link that has died. Write to us through the Contact page with the page address, the sentence or number you believe is wrong and, if you have one, a source we can open ourselves.

When we confirm an error we correct the page and update its review date. If the correction changes what the entry actually says about a product, we add a short note on the page saying what changed. We do not quietly rewrite history.

How often pages are reviewed

Every product entry and post carries the date it was last reviewed. Our working rule is to re-open every Amazon listing we link to at least once a quarter, confirming that the ASIN still resolves to the same product and model, that it is in stock, and that the specifications have not changed, and to re-check a price whenever we touch a page for any reason. Between reviews a listing can change without telling us, which is why the date on the page is the only date that counts.
