What we test

What we test, in plain English.

What each one is, why it matters, how we find it, and how it usually gets fixed.

01 · Water

PFAS

Forever chemicals

PFAS are chemicals used in non-stick pans, stain-proof fabric and firefighting foam. They don’t break down, so they build up in water and in our bodies. That’s why they’re called “forever chemicals.”

Why it matters

The EPA links some PFAS to health problems and now limits two of the most common ones in drinking water.

How we test

We take a sample from your kitchen tap. A certified lab checks it for PFAS and compares it with the EPA limit of 4.0 parts per trillion.

How it’s usually fixed

Usually a certified under-sink filter. We’ll tell you which kind actually removes PFAS.

The EPA set its limits in 2024. Water utilities have until 2029 to meet them, and the EPA has proposed giving some until 2031. Testing your own tap tells you where you stand today.

Microplastics

Tiny pieces of plastic, often too small to see, that show up in tap water and bottled water.

Why it matters

Scientists are still studying what they do in the body, and there’s no official safe limit yet. We give you a count, not a scare.

How we test

A lab filters a sample of your tap water and counts the particles by size.

How it’s usually fixed

Testing before and after your filter shows whether it’s working.

03 · Air

VOCs + formaldehyde

CheckQuick check

Whole HomeLab test, 1 room

PremiumLab test, 2 rooms

Chemical fumes

VOCs are gases that come off paint, new furniture, flooring, cleaning sprays, air fresheners and candles. Formaldehyde is the best-known one. New homes and new furniture often have the most.

Why it matters

The EPA says VOCs can irritate your eyes, nose and throat and cause headaches. Levels are usually higher indoors than outside.

How we test

Every plan checks each main room. Whole Home and Premium add a lab sample that names exactly which chemicals are in the air.

How it’s usually fixed

Usually free or cheap: more fresh air, airing out new furniture, and swapping a few products.

04 · Air

PM2.5

CheckSpot check

Whole Home+ 2 monitors

Premium+ 3 monitors

Fine dust and smoke

Tiny particles of smoke and dust, far thinner than a hair. Scientists call them PM2.5. Indoors, cooking is often the biggest source.

Why it matters

The EPA says these particles are small enough to get deep into your lungs, and some can reach your bloodstream.

How we test

We check every main room. Whole Home and Premium leave small monitors for 5 days and test while you cook.

How it’s usually fixed

Often a range hood that vents outside, or a better filter in your AC.

05 · Air

CO₂

CheckSpot check

Whole Home+ 5 days

Premium+ 5 days

Stale air

We measure carbon dioxide (CO₂) because it’s the best sign of how much fresh air a room gets. In a closed bedroom it can climb all night.

Why it matters

Stale air is a sign that whatever is released indoors, from fumes to fine dust, is staying indoors too.

How we test

We check every main room, then leave monitors for 5 days to catch what happens overnight.

How it’s usually fixed

Often free: crack the bedroom door, or adjust your AC’s fresh-air setting.

06 · Air

CheckIncluded

Premium+ garage

Carbon monoxide

A gas you can’t see or smell. It comes from anything that burns fuel: gas stoves, water heaters, cars in an attached garage, generators.

Why it matters

High levels are dangerous. Your CO alarm warns you about high levels, but it won’t tell you about low, ongoing ones.

How we test

A sensitive meter in every main room and at every gas appliance, water heater and garage door.

How it’s usually fixed

Service or repair the appliance that’s leaking, or seal the garage door.

07 · Dust

Dust mites, pets

CheckAdd-on

Whole HomeAdd-on

PremiumIncluded

Allergens

Tiny proteins from dust mites, pets and cockroaches that settle into beds, carpets and couches. Dust mites love humid homes.

Why it matters

They’re common triggers for allergies and asthma.

How we test

We vacuum a small dust sample from your bed and living room. A lab measures dust mite, cat, dog and cockroach allergens.

How it’s usually fixed

Mattress covers, hot washes, and keeping humidity in check.

08 · Water

In tap water

Check47 tested

Whole Home109 tested

Premium109 + 2nd tap

Lead and heavy metals

Lead, arsenic, copper and other metals. Lead usually comes from the pipes and fixtures inside your home, not the water plant, so you only find it by testing your own tap.

Why it matters

The EPA says there’s no safe level of lead in drinking water. Its health goal is zero.

How we test

A certified lab tests your kitchen tap: 47 contaminants with Check, 109 with Whole Home and Premium.

How it’s usually fixed

Usually the right filter, running the tap before use, or replacing an old fixture.

Also measured

Also part of the visit

Gas & propane homes

Gas stove fumes

Gas burners give off nitrogen dioxide (NO₂), a gas that can irritate your airways. We measure it while you cook. Whole Home and Premium also check the nearest bedroom, with and without the range hood.

Every room

Humidity and temperature

We record humidity room by room and note damp or musty conditions. We don’t assess mold. If we see signs of a moisture problem, we refer you to a licensed mold assessor.

Whole Home & Premium

Household products audit

A walk through cleaners, fragrances, candles and cookware, with simple swaps ranked by impact.

Every water panel

General water quality

Chlorine byproducts, nitrate, hardness and more, so you can pick a filter that actually fits your water.

What we don’t do

What we leave out, and why

Mold

Florida requires a licensed mold assessor to sample for or assess mold. We don’t do either. We note humidity and moisture and refer you to a licensed assessor.

Radon

Radon testing in Florida needs a state-certified tester. We’ll point you to one.

EMF

The science doesn’t support health claims at household levels, so we don’t test for it.

Selling fixes

No filters, purifiers or remediation, and no contractor commissions. That keeps our advice independent.
