Smokeless Chimney

Who Is Behind the Company

Smokeless Chimney is a solo-founder venture led by Noel Putaansuu. No other senior team members are publicly disclosed.

Inside the Company

Smokeless Chimney operates as a trade name for Acumentor LLC, a Washington State limited liability company based in Centralia [Secretary of State]. The venture was founded in 2018 by Noel Putaansuu, who serves as its president and business owner [The Fire Time Podcast, Oct 2021] [LinkedIn, retrieved 2025]. Putaansuu has leveraged a career in fire investigation and insurance spanning more than 35 years to identify a technical problem in residential wood combustion [Seattle Angel Conference] [LinkedIn].

A patent application for monitoring smoke opacity and controlling a wood stove based on that measurement was filed in 2018 [freepatentsonline.com, 2018]. By 2021, the company was presenting its concept as a hardware and sensor platform aimed at improving wood stove efficiency and reducing emissions [InnovateFPGA, Oct 2021]. The most recent public signal is the addition of a firmware engineering intern in October 2025 [LinkedIn, retrieved 2025]. No institutional funding rounds, major customer deployments, or formal partnerships have been disclosed.

Under the Hood

Smokeless Chimney’s public positioning centers on a hardware and sensor platform designed to retrofit existing wood stoves. The company states its core function is to “make hardware to make wood stoves move air out of the home” and to provide “the science to measure smoke from wood stoves” [Smokeless Chimney]. Its primary claimed product is a retrofit combustion control system [Smokeless Chimney]. The technology stack involves embedded firmware and sensor integration [LinkedIn].

The platform’s proposed capabilities include smoke measurement, combustion control, power generation from exhaust heat, and air quality monitoring [Smokeless Chimney]. A foundational patent application from 2018 details a method for “monitoring opacity of smoke exhausted by wood stove and controlling wood stove based on same” [freepatentsonline.com, 2018]. The company’s YouTube channel hosts demonstration videos aimed at showing how its products can reduce smoke and improve safety [Smokeless Chimney - YouTube].

Market Research

The market for wood stove performance and emissions control is driven by a tension between the economic appeal of wood heat and regulatory pressure to curb its environmental impact.

Smokeless Chimney’s addressable market is anchored by the installed base of existing wood stoves. According to a 2021 presentation, there are an estimated 10 million existing wood stoves in the United States [InnovateFPGA, Oct 2021]. The serviceable market is defined by homeowners seeking to improve efficiency and safety, a demand driver underscored by the founder’s work on improving stove performance [CleanTech Alliance, Dec 2022].

Demand tailwinds include rising energy costs and a desire for off-grid resilience. Additionally, particulate matter (PM2.5) from residential wood burning is a recognized contributor to local air pollution, prompting municipalities to consider stricter emission controls or burn bans. The company’s focus on measuring smoke opacity addresses this regulatory vector, as opacity is a legally defined metric for emissions compliance [Smokeless Chimney].

Competition and Substitutes

Smokeless Chimney's competitive position hinges on a hardware wedge in a market dominated by stove manufacturers and generic air quality monitors.

• Incumbent stove manufacturers. Companies like Jøtul, Morsø, and Hearthstone Technologies design and sell high-efficiency wood stoves with integrated combustion systems. Smokeless Chimney's retrofit approach targets the installed base but does not compete for new stove sales.
• Smart stove accessories. Aduro offers the Smart Response system, an intelligent thermometer and damper control that connects to a mobile app [Adurofire.com]. This represents a direct, feature-level competitor focused on automation, though it does not claim the smoke measurement and opacity monitoring central to Smokeless Chimney's patent.
• Air quality sensor companies. Companies like Airthings, Awair, and PurpleAir measure particulate matter (PM2.5) but are designed for ambient room or outdoor monitoring, not for direct, in-stack measurement of combustion opacity.
• Regulatory and testing labs. The founder's background in fire investigation intersects with a niche of certified testing organizations that verify stove emissions for EPA compliance. These are service providers, not product competitors.

Data Accuracy: YELLOW -- Competitor identification is inferred from adjacent markets; Smokeless Chimney's unique claims are sourced from its own website and a patent application.

Opportunity

The opportunity for Smokeless Chimney rests on the potential to retrofit a portion of the 10 million existing wood stoves in the United States with its proprietary control and measurement hardware.

The headline opportunity is the creation of a retrofit standard for wood stove emissions control. The company has staked an IP position with a patent application for monitoring and controlling smoke opacity [freepatentsonline.com, 2018], targeting a fragmented installed base of legacy appliances. The core technology addresses a regulatory and environmental pain point: reducing particulate emissions from residential wood burning.
