VOC Levels: The Real Numbers

Both paints are labeled “zero-VOC,” but the details matter.

Benjamin Moore Natura tests at 0 g/L in the base formula, and the critical difference is that Benjamin Moore reformulated their entire colorant system to be zero-VOC as well. This means that regardless of the color you choose, from the palest white to the deepest charcoal, the tinted paint stays at 0 g/L. This is a significant engineering achievement and one of Natura’s strongest selling points.

Sherwin-Williams Harmony also tests at 0 g/L in the base formula. However, the colorant system is where things get murkier. Sherwin-Williams uses a universal tinting system across many of their product lines. Depending on the specific color and how much colorant is required, tinted Harmony can pick up additional VOCs. Light colors stay close to zero. Deep, saturated colors can creep up to 10-20 g/L after tinting.

For white or very light colors, the difference is negligible. For medium to dark colors, Natura has a measurable advantage in terms of actual VOC content in the finished paint.

Winner: Benjamin Moore Natura. The zero-VOC colorant system keeps the paint clean regardless of color choice.

Coverage and Application

Benjamin Moore Natura covers approximately 400-450 square feet per gallon, which is on the higher end for zero-VOC paints. The formula is rich and smooth with a consistency that’s easy to work with. It self-levels well, which helps minimize brush marks and roller stipple. Two coats are sufficient for most color changes, including going from a darker shade to a lighter one. The paint is self-priming on previously painted surfaces in good condition, which saves a step and reduces cost.

Sherwin-Williams Harmony covers approximately 350-400 square feet per gallon, which is respectable but slightly lower than Natura. The formula goes on smoothly and is easy to work with. It doesn’t self-prime, so you’ll need a separate primer on new surfaces or when making significant color changes. Two coats are standard for most applications; going from dark to light may need three.

In practice, the coverage difference means Natura will use roughly 10-15% less paint for the same room. On a typical bedroom project requiring two gallons, that translates to needing slightly less touch-up or having more paint left over. Not a huge difference, but it adds up on larger projects.

Both paints dry to the touch in about an hour and can be recoated in 2-4 hours. Full cure takes about 30 days for both.

Winner: Benjamin Moore Natura. Better coverage per gallon and self-priming capability give it an edge.

Durability and Washability

This category matters because a paint that wears out faster means more frequent repainting, which means more chemicals in your home over time.

Benjamin Moore Natura in eggshell finish offers good scrub resistance. You can wipe down walls with a damp cloth and mild soap without damaging the finish. It resists scuffing well in normal residential use and holds up to the occasional furniture bump or hallway traffic. The semi-gloss finish is even tougher and works well on trim, doors, and high-moisture areas.

Sherwin-Williams Harmony is comparable in durability for most finishes. The satin finish (which Natura doesn’t offer as a separate option between eggshell and semi-gloss) provides a nice middle ground for durability and appearance. Harmony’s antimicrobial technology gives it a meaningful advantage in bathrooms, basements, and other spaces where mold and mildew are concerns. The paint resists microbial growth on the paint film itself, which can extend the time between repaints in humid environments.

For most rooms in a typical house, durability is comparable. In bathrooms and humid spaces, Harmony’s antimicrobial properties provide a functional advantage that Natura doesn’t match.

Winner: Tie overall. Harmony edges ahead in bathrooms and humid spaces. Natura performs equally well in standard living areas.

Color Selection

Benjamin Moore Natura gives you access to Benjamin Moore’s full color library, which includes over 3,500 colors. This is one of the most extensive color systems in the paint industry, and it includes popular palettes and designer collections. The color accuracy is excellent because Benjamin Moore controls the entire formulation and tinting process in-house.

Benjamin Moore also offers digital color matching tools and physical fan decks that are well-regarded by designers and paint professionals. If you find a color you like in a magazine or another brand’s palette, Benjamin Moore can typically match it.

Sherwin-Williams Harmony offers access to over 1,700 colors, which is still a large selection but roughly half of what Benjamin Moore provides. Sherwin-Williams has strong color tools including their ColorSnap system and physical color chips. Their palette includes popular collections and trend-forward selections.

Color accuracy with Harmony is generally good but can vary slightly because the universal tinting system wasn’t designed specifically for the Harmony formula. Most consumers won’t notice the difference, but color-sensitive professionals sometimes report that Benjamin Moore’s dedicated tinting produces more accurate results.

Winner: Benjamin Moore Natura. Double the color selection plus zero-VOC colorants for any shade.

Price Comparison

Here are the real costs for a typical project - painting a 12x14 bedroom with 8-foot ceilings (roughly 400 square feet of wall space).

Benjamin Moore Natura:

  • Paint: 2 gallons at $55-$70 = $110-$140
  • Primer: Often not needed (self-priming) = $0
  • Total paint cost: $110-$140

Sherwin-Williams Harmony:

  • Paint: 2 gallons at $50-$65 = $100-$130
  • Primer (if needed): 1 gallon at $40-$50 = $40-$50
  • Total paint cost: $100-$180

Without primer needs, Harmony saves you $10-$20 on the paint alone. But if you need a primer (new drywall, significant color change, stain blocking), Natura’s self-priming capability could save you $40-$50 or more. This makes Natura the better value for many projects despite the higher per-gallon cost.

Both brands run sales regularly. Sherwin-Williams is particularly known for their 30-40% off sales that happen several times per year. If you can time your purchase, Harmony during a sale is significantly cheaper than Natura at retail price.

Winner: Depends on the project. Harmony has a lower per-gallon price. Natura often costs less overall thanks to self-priming.

Availability

Sherwin-Williams Harmony is the clear winner here. Sherwin-Williams operates over 4,000 company-owned stores across the United States. Most mid-size towns have at least one location. You can walk in, get your paint mixed, and walk out in 15 minutes. The stores are staffed by people who know their products and can offer mixing and application advice.

Benjamin Moore Natura is available through approximately 3,500 independent dealer locations. These are locally owned paint stores and hardware stores that carry Benjamin Moore products. Coverage is good in most urban and suburban areas, but it’s spottier in rural areas. You can’t buy Natura at Home Depot, Lowe’s, or other big-box retailers. Benjamin Moore’s store locator on their website helps you find the nearest dealer.

Both brands can ship paint, but ordering paint online means waiting for delivery and dealing with heavy, sometimes hazardous-material shipping. For most people, buying locally is more practical.

Winner: Sherwin-Williams Harmony. More stores, more consistent availability, and company-owned locations with guaranteed stock.

Special Features

Sherwin-Williams Harmony: Formaldehyde-Reducing Technology

Harmony includes a technology that Sherwin-Williams says actively reduces formaldehyde levels in the room. Formaldehyde is a common indoor air pollutant that off-gasses from pressed wood products, cabinets, and other building materials. The paint uses amine-based chemistry to bond with and neutralize airborne formaldehyde molecules that contact the painted surface.

The underlying chemistry is sound. Amine groups can bind with formaldehyde, and this reaction is well-documented. The practical question is how much formaldehyde a painted wall can actually absorb and whether it makes a meaningful difference in room-level concentrations. Sherwin-Williams doesn’t publish specific data on how much formaldehyde their paint reduces in real-world conditions. The effect is likely modest but genuinely present.

If your home has a lot of pressed wood furniture, newer cabinets, or other potential formaldehyde sources, this feature is a meaningful plus. If your home doesn’t have significant formaldehyde sources, it’s a nice-to-have that probably won’t change your experience.

Sherwin-Williams Harmony: Antimicrobial Protection

Harmony contains antimicrobial agents that inhibit the growth of mold and mildew on the paint film. This is a genuine functional benefit in bathrooms, basements, laundry rooms, and any space with high humidity. The agents are embedded in the paint and remain active for the life of the coating.

The trade-off is that “antimicrobial” means “biocide.” The paint contains chemicals designed to kill microorganisms. For most adults, this is a non-issue. For nurseries or rooms where chemically sensitive individuals spend a lot of time, the presence of biocides is worth considering. This is one reason why specialized nursery paints like Lullaby Paints deliberately exclude antimicrobial additives.

Benjamin Moore Natura: Self-Priming

Natura’s self-priming capability is a practical advantage that saves time, money, and chemical exposure. On previously painted surfaces in good condition, you can apply Natura directly without a separate primer. This eliminates one layer of product and one round of drying and off-gassing.

On new drywall, bare wood, or surfaces with stains, you’ll still need a primer. Benjamin Moore offers zero-VOC primers that pair well with Natura.

The Bigger Picture: Paint Is Just the Start

Whichever paint you choose, it’s worth thinking about what else is going on in your home. The primer, caulk, wood stain, and flooring you choose all affect your indoor air quality. A zero-VOC paint job over a high-VOC primer in a room with new vinyl flooring doesn’t get you where you want to be.

If you’re doing a renovation, our how to detox your home guide provides a room-by-room approach to minimizing chemical exposure. And understanding what VOCs are helps you make better decisions about every product, not just paint.

Quick Answers

Which paint is better for a nursery, Natura or Harmony?

Benjamin Moore Natura is better for nurseries. The zero-VOC colorant system means every color stays at 0 g/L, and the formula doesn’t include antimicrobial biocides. Harmony’s biocides are considered safe by regulatory standards, but for a nursery, minimizing all additives is the safer approach. For dedicated nursery paints, see our best nursery paint guide.

Does Sherwin-Williams Harmony really reduce formaldehyde?

The chemistry behind the claim is legitimate. Amine groups in the paint can bond with formaldehyde molecules on contact. However, Sherwin-Williams doesn’t publish specific data on how much room-level formaldehyde is reduced in practice. The effect is real but likely modest. It’s a meaningful bonus, not a substitute for addressing formaldehyde sources directly.

Can I use Natura and Harmony in the same house?

Absolutely. Many homeowners use Natura for bedrooms and nurseries (where zero-VOC purity matters most) and Harmony for bathrooms and kitchens (where antimicrobial protection is useful). There’s no compatibility issue between the two.

Which paint lasts longer between repaints?

Both are comparable in durability for standard residential use. In humid environments, Harmony’s antimicrobial properties may extend the time between repaints by preventing mold growth on the paint film. In dry environments, performance is essentially identical.

Do either of these paints have GREENGUARD Gold certification?

Neither Natura nor Harmony holds GREENGUARD Gold certification for the paint product itself. If GREENGUARD Gold certification is important to you (especially for nurseries or schools), Clare Paint is the zero-VOC option that carries this certification.

Is the price difference worth it?

For a single room, the price difference between Natura and Harmony is $10-$20 at most. On a whole-house project, it could be $100-$200. Whether that’s “worth it” depends on your priorities. If zero-VOC colorants and color accuracy matter to you, Natura’s premium pays for itself. If you value convenience and antimicrobial protection, Harmony gives you more for less.
